Answer:

b ≈ 48.6°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin b = \frac{opposite}{hypotenuse} = \frac{9}{12} , then

b = sin^{-1} (\frac{9}{12} ) ≈ 48.6° ( to 1 dec. place )

alekssr [168]
Ok, so yo know what a net is? (not like fishing) like when you unfold the shape

ok so

the left side box surface area is
SA=2(LW+LH+WH)
SA=2(35*12.5+35*32.5+12.5*32.5)
SA=2(437.5+1137.5+406.25)
SA=2(1981.25)
SA=3962.5 cm^2

the right shape (triangular psism)
has 2 triangles and 3 rectangles
SA=2(1/2bh)+2(slantheight times side)+bh
SA=(23 times 20.5)+2(23.5 times 12.5)+(23 times 12.5)
SA=471.5+2(293.75)+287.5
SA=759+595.5
SA=1346.5

box=3962.5 cm^2
trianglar ting=1346.5 cm^2
how much more
box-triangle=3962.5-1346.5=2616 cm^2 more

I need help with 7 and 8. Thank you sm!
Arte-miy333 [17]
Well number 7 would be 70° because it's the same angle as the one that's labeled 70°.

Number 8 would be G, alternate exterior angles. They're not on the inside, which makes them on the outside, which is the exterior. And they are not on the same side, which makes them alternate and not corresponding.
