What is the value of x? A. 142 B. 152 C. 76 D. 71
1 answer:
Answer:
x has a value of 71, making D the correct answer.
Step-by-step explanation:
Because this is an isosceles triangle, we know that the bottom two angles are equal. We also know that the sum of the angles inside a triangle will always come to 180°. With that in mind, we can simply subtract 38° from 180° and divide by two to get the correct answer.
So the correct answer is D, 71 degrees.

Answer:
−438°, -78°, 642°
Step-by-step explanation:
Given angle:
282°
To find the co-terminal angles of the given angle.
Solution:
Co-terminal angles are all those angles having same initial sides as well as terminal sides.
To find the positive co-terminal of an angle between 360°-720° we will add the angle to 360°
So, we have:
To find the negative co-terminal of an angle between 0° to -360° we add it to -360°
So, we have:
To find the negative co-terminal of an angle between -360° to -720° we add it to -720°
So, we have:
Thus, the co-terminal angles for 282° are:
−438°, -78°, 642°
