Answer:

x=52

Step-by-step explanation:

r=90 s=34 q=180-(90+34)

180-(90+34)=56

to find angle sqr

180-56=124

124=x+72

52=x

Answer:

x = 52

Step-by-step explanation:

→We are given an exterior angle (outside of the triangle) as (x + 72). We are also given two interior angles as 34 and 90. The sum of the two farthest interior angles away from the exterior, is equal to the exterior. So this means that ∠R(90°) + ∠S(34°) = ∠PQS(x + 72), and we can set up the equation like that:

90 + 34 = x + 72

<u>→Add like terms (90 and 34):</u>

124 = x + 72

<u>→Subtract 72 from both sides:</u>

52 = x

Step-by-step explanation:

The formula for finding the combination of two given positive numbers is given by

Where n and r are positive numbers

From the question we have

5 C 3

<u>Simplify</u>

That's

<h3> $\binom{5}{3} = \frac{5!}{(5 - 3)!3!} = \frac{120}{2! \times 3 !} \\ = \frac{120}{2 \times 6} \\ = \frac{120}{12}$ </h3>

We have the final answer as

Answer:

1296mm^2

Step-by-step explanation:

Surface Area of the Rectangular Prism to the left on top of the box:

Area of square = lw, 9mm * 9mm = 81mm, then multiply by 2 because 2 of the squares are a part of the surface, giving <u>162mm^2</u>

Area of a rectangle =lw, 9mm * 9mm = 81mm, then multiply by 2 again, because 2 rectangles are a part of the surface, giving <u>162mm^2</u>

So, the total surface area of the rectangular prism to the left on top, is 324mm^2

Surface Area of the Triangular Prism:

Area of a triangle: 1/2bh, and our base length would be 12, because we have to subtract 9 from 21 since the base length of the triangle isn't stated. Anyways, A = 1/2bh, so A = 1/2(12)(9) = 54mm^2, but multiply by two, so we get <u>108mm^2</u>.

Area of the rectangle: lw, so 15mm * 9mm = <u>135mm^2</u>

So, the total surface area of the triangular prism is 243mm^2

Surface Area of the Rectangular Prism at the bottom:

Area of the long rectangles in front = lw, 21mm * 9mm = 189mm^2, multiply by 2, <u>378mm^2</u>

Area of the rectangles to the side = lw, 9mm * 9mm = 81mm^2, multiply by 2, <u>162mm^2 </u>

Area of the rectangle at the very bottom = lw, 21mm * 9mm = <u>189mm^2</u>

So, the total surface area of the rectangular prism at the bottom is 729mm^2

Add all the total surface areas of each shape to get the total surface area of the figure:

324mm^2 + 243mm^2 + 729mm^2 = 1296mm^2

The surface area of the figure above is 1296mm^2

Find the total area of the figure. It is _______ square inches.

kompoz [17]

Answer:

1100 square inches

Step-by-step explanation:

Formula: LxW

<u>Smallest rectangles</u> area: 5*20=100= 1 rectangle

there are 2 smal rectangles so= 100*2=200

<u>Medium rectangles</u> area: 5*30=150

There are 2 so= 150*2= 300

<u>Biggest rectangle:</u> 30*20= 600

Total Area: 200+300+600= 1100 square inches
