Answer:

a = 50, b = 70

Step-by-step explanation:

In a parallelogram, opposite angles are congruent so we can write the following equation to solve for b:

b + 20 = 2b - 50

-b = -70

b = 70

To solve for a:

a + 40 = 2a - 10

-a = -50

a = 50

Step-by-step explanation:

Step 1: Define

f(x) = 2x + 1

g(x) = 3x - 2

Step 2: Find g(1)

Substitute in x: g(1) = 3(1) - 2
Multiply: g(1) = 3 - 2
Subtract: g(1) = 1

Step 3: Find f[g(1)]

Substitute in g(1): f[g(1)] = 2(1) + 1
Multiply: f[g(1)] = 2 + 1
Add: f[g(1)] = 3
