Two complementary angles are in the ratio 7:8. What is the measure of the larger angle?

yan [13]

Answer

Step-by-step explanation:

We know that sum of complementary angle adds to 90°

Let the angles be 7x and 8x

First of all, finding the value of x

$\sf{7x + 8x = 90 °}$

Collect like terms

⇒ $\sf{15x = 90 °}$

Divide both sides of the equation by 15

⇒ $\sf{ \frac{15x}{15} = \frac{90}{15} }$

Calculate

⇒ $\sf{x = 6 °}$

The value of X is 6°

Now, substituting / Replacing the value of x

⇒ $\sf{7x = 7 \times 6 = 42}$

⇒ $\sf{8x = 8 \times 6 = 48}$

The measure of larger angle is 48°

Hope I helped!

Best regards!!

Answer:

a. 2x -3

b. 7

Step-by-step explanation:

a. The expression that represents the difference is sales between the two sales will be:

9x - (7x + 3) = 9x - 7x - 3 = 2x - 3

b. What we do here is to simply substitute the value of 5 for x

mathematically, we have to substitute the value of 5 in the expression above

We have this as:

2(5) -3

= 10-3 = 7
