Surface area = 2(wl + hl + hw) = 2wl + 2hl + 2hw
Conditions:
base length is shrunk by a factor of 2/3
width is quadrupled
height is cut in half.
l ⇒ 2l/3 w ⇒ 4w ; h ⇒ h/2
SA = <span>2wl + 2hl + 2hw
</span>SA = 2(4w)(2l/3) + 2(h/2)(2l/3) + 2(h/2)(4w)
SA = (16wl/3) + 4hl/6 + 8hw/2
Simplify:
SA = 16/3 wl + 2/3 hl + 4hw Choice C.
Answer:
95 degrees
Step-by-step explanation:
in a triangle angles add up to 180 degrees.
a + b + c = 180
30 + 45 + c = 180
85 + c = 180
c= 180 - 85
c= <u>95 degrees</u>
