Answer:
no angle c is not supplementary
Step-by-step explanation:
Angle A and angle B are supplementary
A+B=180° Equation 1
The measure of angle B is equal to four times the complement of angle A
The complement of angle A=90°-A
B=4(90°-A)
B=360°-4A
Substitute the value of B in equation 1
A+360°-4A=180°
-3A=-180°
A=60°
The measure of angle A=60°
B=360°-4A=360°-4(60°)=120°
The measure of angle B=120°
Answer:
ok so to solve this you need to do base x height then divide that by 2
Step-by-step explanation:
Answer:
whaaaaaaaaaattt????
Step-by-step explanation:
To find the value of x we first need to find the missing angle in the triangle.
To do that we are gonna add the angles we already have.
64 + 45 = 109
Angles in a triangle measures 180 so to get the missing angle we are gonna subtract 109 from 180
180 - 109 = 71 deg
The missing angle in the triangle is 71 deg
Angles on a straight line adds up to 10 so to find x we are gonna subtract 71 from 180
180 - 71 = 109 degrees
Therefore x is 109 degrees.
