Answer:
168 cm²
Explanation:
Lateral surface area of triangular prism: (perimeter of base) × height
Here given:
So, lateral surface area:
= (4 + 6 + 4) × 12
= 168 cm²
Answer:
-2 will be the answer I think it will help so much my answer
I hope this helps you
tanA= height /base= -3/1
3^2+1^2=hypothenus ^2
hypothenus =squeare root of 10
sinA=height /hypothenus
sinA=3.square root of 10/10
Initially started 20 feet from the ground .
Went uphill 83 feet.
So: 20 + 83 = 103. The coaster is 103 ft above at this point.
Went down 42 feet
So: 103 - 42 = 61.
Went up 128 feet
So: 61 + 128 = 189
Finally, went down 90 feet
So: 189 - 90 = 99
99 ft above ground.
