Answer:
m<1 = 76°
m<2 = 104°
m<3 = 76°
m<4 = 104°
Step-by-step explanation:
m<1 and m<3 are vertical angles so, these angles have the same measure of 76°. m<2 and m<4 are also vertical angles which have the same measure. To find m<2, use m<1. m<1 and m<2 are <u>supplementary angles</u> which add up to 180°. Subtract 180 from 76 which is 104.
The answer is acute triangle because none of the angles are greater than 90°
Since the line goes through (0, 0), it can be described by
y = kx
You are given the point (12, 72), so you know
72 = 12k
6 = k . . . . . . . divide by 12
Then the equation of the line is ...
y = 6x
Answer:
BC = 20
Step-by-step explanation:
If all angles are the same then all the sides are the same; therefore, BC = AC.
Set up the equations to solve for y
-y + 23 = 6y + 2; add y to both sides
23 = 7y + 2; subtract 2 from both sides
21 = 7y; divide by 7
y = 3; now use this to substitute into term for BC = 6y + 2 = 6(3) + 2 = 18+2 = 20
