Answer: 1/2 of 12 = 1/4 of 24 and 1/3 of 90 = 2/3 of 45
Step-by-step explanation:
If I were you I would go onto Desmos and graph these two equations
Answer:
Step-by-step explanation:
The vertices of the trapezoid are the origin along with A(4a, 4b), B(4c, 4b), and C(4d, 0). Find the midpoint of the midsegment of the trapezoid
Answer:
12
Step-by-step explanation:
20²-16²=400-256=144
√144=12
Complimentary angles add to equal 90°. Write two equations to solve for two variable.
J + K = 90
J = K - 18
use substitution or elimination to solve
I will use substitution. substitute (K - 18) for J in the first equation to combine equations into one in only variable K.
(K - 18) + K = 90
2K - 18 = 90
2K = 90 + 18
2K = 108
K = 108/2
K = 54°
J and K are complimentary.
J + 54° = 90°
J = 36°
