If the difference between the measures of the two smaller angles of a right triangle is 20 degrees what is the measure, in degre

nordsb [41]

Answer:

Measure of the smallest angle = 35 degrees.

Step-by-step explanation:

As it is a right triangle the values of the 2 smaller angles will add up to 90 degrees.

So the 2 angles can be written as x and 90-x and we have:

(90 - x) - x = 20

-2x = 20 - 90 = -70

x = 35.

So the 2 angles are 35 and 55 degrees.

What is the area of a pizza with a diameter of 12 inches? Round to the nearest tenth. Use 3.14 for pi.

Flauer [41]

Answer:

$\boxed {\boxed {\sf a \approx 113.0 \ in^2}}$

Step-by-step explanation:

Assuming this pizza is a circle, we can use this formula for area:

$a= \pi r^2$

1. Find Radius

We are given the diameter: 12 inches, but the formula uses radius.

The radius is half the diameter, or:

$r=\frac{d}{2}$

$r=\frac{12 \ in}{2}$

$r= 6 \ in$

2. Calculate Area

Substitute the radius (6 inches) in for r. The question also asks us to use 3.14 for pi.

$a= (3.14)(6 \ in)^2$

Solve the exponent.

(6 in)²= 6 in* 6 in= 36 in²

$a= (3.14)(36 \ in^2)$

Multiply.

$a= 113.04 \ in^2$

3. Round

The question asks us to round to the nearest tenth.

The 4 in the hundredth place tells us to leave the 0 in the tenth place.

$a \approx 113.0 \ in^2$

The area of the pizza is about 113.0 square inches.
