Answer:
Step by step explanation:
Let x be the angle. The complement is 3x + 10. The sum of two complementary angles is 90. So,
x + 3x + 10 = 90
4x + 10 = 90
4x = 80
x = 20
Plug x into the complement
3(20) + 10 = 70
The angle is 20 degrees and the complement is 70 degrees
Answer:
y=2x+7
Step-by-step explanation:
Equation of line: y = mx + b
where m is the slope, and b is the y-intercept
Answer:
Im pretty sure its 45 degrees
Step-by-step explanation:
Its an isosceles triangle so the upper 2 angles are Equal and a triangles angles adds up to 180 degrees, so if we have a 90 degree angle (the square) there's only 90 degrees left, so if you divide the 90 degrees by the remaining 2 Equal angles you get 45.
