The angle above the y is 90 degrees ( shown by the little square)
The 3 inside angles of a triangle need to equal 180.
Y = 180 - 90 - 48
Y = 42

17a²b
Answer:
Step-by-step explanation:
#6
a n
---- = ---- Solve for a. Note that if we multiply both sides of this equation by
m p n
m, we get a = m * ----
p
m*n
and this simplifies to a = mn/p or a = ---------
#7 Solve mx = np for x. We want to isolate x on the left side. Dividing
both sides by m isolates x on the left and adds the divisor m on the right:
np
mx = np => x = ------
m
#8 Solve c - x = d + r for x We want -x alone on the left side. Accomplish this by subtracting c from both sides, obtaining:
-x = d + r - c. Now multiply both sides by -1, obtaining x = -d - r + c
