What is the surface area of this right prism?<br><br> Enter your answer in the box.<br><br> cm²

fomenos

Answer:

<h2>the answer is</h2><h2>166 cm²</h2>

Step-by-step explanation:

we know that

surface area of the prism=2*area of the base+perimeter of the base*height

step 1

find the area of the base

area of the base=length* width

length=5 cm

width=4 cm

area of the base=5*4-----> 20 cm²

step 2

find the perimeter of the base

perimeter=2*[length+width]-----> 2*[5+4]----> 18 cm

step 3

height=7 cm

step 4

find the surface area

surface area of the prism=2*area of the base+perimeter of the base*height

surface area of the prism=2*20+18*7----> 166 cm²

If 2xº and (2x - 20) are a pair of adjacent supplementary angles, find the<br>value of x.

kifflom [539]

Answer:

x = 50

Step-by-step explanation:

Since the two angles are supplementary, add them together and set them equal to 180 degrees

2x + 2x - 20 = 180 Combine like terms

4x - 20 = 180

+ 20 + 20 Add 20 to both sides

4x = 200 Divide both sides by 4

x = 50

Base of triangle exceeds the height by 4. If the area is 178.5 square inches, find the length of the base and the height of the

xxMikexx [17]

Area of a triangle:
A= (1/2)(bh)

In this problem we are given:
A= 178.5 $in^{2}$
b= h+4 in
h= UNKNOWN ("h")

Plug in our values into the area equation and solve for "h":
$A= \frac{1}{2} bh$
$178.5 = \frac{1}{2} ((h+4)h)$ (multiply each side by 2 to get rid of the 1/2)
$357 = ((h+4)h)$
$357 = h^{2} +4h$
$0= h^{2} +4h -357$
(357/21=17)
$0= (h+21)(h-17)$ (solve both inequalities separately)

$0= (h+21)$
$-21= h$ ( a negative height is not possible so, this answer is incorrect.)

$0=(h-17)$
$h=17 in$

Answer: base = (h+4)= (17+ 4) b= 21 in h= 17in
