Answer:

Wendy = W

Connie = C

Tim = T

Equations

W = C + 4

C = T + 4

W + C + T = 45

Solution

Put W into the third equation

C + 4 + C + T = 45

2C + 4 + T = 45

Put T into the above equation

C = T + 4

T = C - 4

2C + 4 + C - 4 = 45

3C  = 45

C = 15

C = T + 4

15 = T + 4  The answer is: 11 = T

Use the diagram to answer the question. What is the measure of ∠A? Enter the correct value. Do not enter the degree symbol.
forsale [732]

Answer:

Measure of ∠A = 60.07°

Step-by-step explanation:

From the figure attached,

ΔABC is a right triangle,

Measure of side AC = 15 units

and measure of side BC = 13 units

By applying Sine rule in this triangle,

SinA = \frac{\text{Opposite side}}{\text{Hypotenuse}}

Opposite side of angle A = Side AC

and hypotenuse of the triangle = Side BC

SinA = \frac{13}{15}

    A = \text{Sin}^{-1}(\frac{13}{15})

    A = 60.07°

Therefore, measure of angle A is 60.07°.
