Step-by-step explanation:

x = 59°

Step-by-step explanation:

The square symbol shown in the angle means that it is 90°. We can say that the angle x - 7 and 38 add up to 90 because of that. We can set up an equation to model the situation:

x - 7 + 38 = 90

x + 31 = 90

x = 59°

d=100

Step-by-step explanation:

.99d=10 + .89d

subtract .89d from both sides

.1d=10

divide by .1 on both sides

d=100

to check plug in 100 in place of d
