Answer: k = 5°
Step-by-step explanation:
- A triangle adds up to 180°. Therefore, the equation is 115 + (4k + 5) + (6k + 10) = 180.
- Remove the parenthesis and combine the like terms. 115 + 5 + 10 = 130 and 4k + 6k = 10k. The equation simplifies to 130 + 10k = 180.
- Subtract 130 on both sides. 10k = 50
- Divide by 10 on both sides. k = 5
Answer:
105IN^2
Step-by-step explanation:
surface area of a square pyramid formula: 2bs+b^2
where s=slant height
and
b=base
so
2(5)(8)+5^2=
80+25=106
105in^2
