Charles draws a supplementary angle and partitions it into 4 smaller angles totaling 180° . Angle X and Angle Y have the same measurement. Angle Z is 250% the value of Angles X and Y. Angle W is half the value of Angle X. Write an expression to determine the measurement of each angle.

w= 18° , x= 36°, y= 36°, z= 90°

Step-by-step explanation:

Let angle x be denoted as x

Since Angle X and Angle Y have the same measurement. This means: x = y

Angle Z is 250% the value of Angles X and Y. This means:

z = 250% × x = 2.5x

Angle W is half the value of Angle X. This means:

w = 1/2 × x = 0.5x

Add all the angles together and recall that:

w = 0.5x

x = x

y = x

z = 2.5x

W + X + Y + Z = 180

0.5x + x + x + 2.5x = 180

5x = 180

x = 180/5

x = 36°

w = 0.5x = 0.5 × 36° = 18°

x = x = 36°

y = x = 36°

z = 2.5x = 2.5 × 36° = 90°

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.
