Answer:

The surface area of the prism is 310

Step-by-step explanation:

1. SA= 2(lw+lh+wh) / SA= 2(10*7+10*5+7*5)

2. 1) SA= 2(10*7+10*5+7*5)

2) SA=2(70+50+35)

3) SA=2*155

4) SA=310

3. The surface area is 310

Hope this helps/ is right :)

Hi there! :)

a) (ii) The two angles are vertical angles, so they are congruent.

b)(i) y = 71°

(ii) The two angles are alternate interior angles, so they are congruent.

c) z = 44°

(ii) m∠x = 65° because the two angles are vertical angles, so they are congruent.

b) (i)

∠y is an alternate interior angle, therefore:

m∠y = 71°

c) Use the sum of interior angles of a triangle to determine the measure of angle z:

180 = 65 + 71 + z

180 = 136 + z

180 - 136 = z

z = 44°.

a circle has a radius of 9 inches. In inches, what is the length of the arc intercepted by central angle of 3.25 radians

frutty [35]

Answer:

$\boxed {\boxed {\sf 29.25 \ inches}}$

Step-by-step explanation:

Since we are given the central angle in radians, we should use the following formula for the arc length.

$s= \theta r$

Where s is the arc length, θ is the angle in radians, and r is the radius.

We know this circle has a radius of 9 inches and the central angle is 3.25 radians.

θ= 3.25
r= 9 in

Substitute the values into the formula

$s= (3.25)( 9 \ in)$

Multiply.

$s= 29.25 \ in$

The arc length is 29.25 inches.

4. Angles A and B are supplementary. If mA = 67, find mB

qaws [65]

Answer:

113 degrees

Step-by-step explanation:

Two angles are called supplementary when they add up to 180 degrees

$180 = x + y \\ 180 = 67 + y \\ y = 180 - 67 \\ y = 113 \\ therefore \: mB \: = 113$
