Well to start off, the cone. It says switch ‘’ to 3 and for r (radius), we know the diameter is 6, and the radius is half of it. So the radius is 3 in.
so far it’s 3•3..to the power of two times ‘H’ (height) the height is 10, as you can see in the picture. So the equation we have so far is:
3•3^2•10 / 3 the answer to that is 90in
For the rectangle, the volume for rectangular prisms is length • width • height
so it’s 8 • 8• 1 which equals, 64 inches.
Now all you got to do is Add both answers.
90+64 = 154 in. That’s the answer

Two angles are supplementary. The measure of the larger angle is 20 degrees

rjkz [21]

Based on the given parameters of the question the correct angles are as follows;

The measure of the large angle is 155°, and the measure of the small angle is 25°

The reasons the above values are correct are given as follows:

The given parameters are;

The properties of the two angles = Supplementary angles (sum of 180°)

The measure of the larger angle = 7 × The measure of smaller angle - 20°

Required:

To find the measure of each angle algebraically

Solution:

An algebraic equation can be described as a mathematical expression having an equal to sign that relates variables representing unknown values or quantities

Let L, represent the measure of the larger angle and let S, represent the measure of the smaller angle, we have;

L + S = 180°...(1)

L = 7 × S - 20°...(2)

Therefore;

Plugging in the value of L from equation (2) in equation (1) gives;

L + S = 7 × S - 20 + S = 180

7·S + S - 20 = 180

Adding 20 to both sides gives;

7·S + S - 20 + 20 = 180 + 20 (addition property of equality)

8·S =180 + 20 = 200

$S = \dfrac{200}{8} = 25$
