What is its supplementary angle if the angle measures 40 degrees?

140° angle
The supplement of a 40° angle is a 140° angle.

What triangle has two 40 degree angles?

Isosceles Triangle
Isosceles Triangle degrees 100, 40, 40 | ClipArt ETC.

What angle measures 40 degrees?

Acute – any angle which measures less than 90 degrees. These angles appear “sharp,” like the blade on a knife. Example: The angle ABC measures 40 degrees. Angle ABC is acute.

Can a triangle have two 40 degree angles?

By definition, an isoceles triangle must have 2 equal sides, and therefore 2 equal angles. Two possibilities: A 40 degree angle at each side, and a 100-degree angle at the top.

What is the supplement of the complement of 40 degrees?

complement angles add to 90 degrees and supplement angles add to 180 degrees. complement angle to 40 degrees is 90 – 40 = 50 degrees and the supplement angle to 40 degrees is 180 – 40 = 140 degrees.

What triangle is 70?

Isosceles triangle
Isosceles triangle, 70 degrees.

What type of triangle has angle measures of 40 50 90?

right triangle
A right triangle with degrees 40, 50, 90.

How do you construct a 40 degree angle?

Steps of Construction:

1. Draw ∠BAC=40o using protractor. By taking A as centre draw an arc which cuts AB and AC at P and Q.
2. Now take O as centre on another line segment EF and taking the same radius PQ draw an arc which cuts OF at R.
3. Join O to S which is the required ∠ROS=40o.

What do you call the triangle whose two angles are 40 and 70?

It is an isosceles triangle. We know this because 40 + 70 = 110. So we take away 110 from 180 (The sum of the three degrees in a triange) to give us the degree of the last angle, which is 70.

Is 40 degrees the complement of 60 degree?

Answer: The given statement is false.

What is the number of degrees in each angle?

A right angle is divided into 3 angles. If one angle is equal to 40 degrees and the other two angles are equal, what is the number of degrees in each angle? A right angle is 90°, one angle is 40°, 90° – 40° = 50°. So the remaining two angles have a total measurement of 50°.

What is the measure of a 50 degree angle?

A right angle is 90°, one angle is 40°, 90° – 40° = 50°. So the remaining two angles have a total measurement of 50°. If these two angles are equal, then each of the remaining angles are 50°/2, or 25°. The three angles are: 40°, 25°, and 25°.

How do you find the angles of an isosceles?

Since two sides of an isosceles are identical, the two angles separated by the base are equal. Back to #1, 180 degrees are in a triangle. Subtract the vertex angle of 40 degrees from the 180 degrees. That leaves 140 degrees. Back to #3, the remaining two angles are identical. Divide that 140 remaining degrees by 2 for 70 degrees each.

How do you find the sin of a 30 degree angle?

From trigonometry we know that Area=1/2 the product of 2 sides and the sine of the included angle. If AB=10 and AC=16 then the included angle is angle A. So 40= ½ (16) (10)sin (A) and thus the sin (A)= ½ and angle A is 30 degrees (or 50 degrees).
