Can someone please help me with this trig question.For a given right triangle, side a = 76.4 feet and side b = 39.3 feet What is the length of side c to the nearest tenth of a foot?
Answers
Let 39.3 be the base of right triangle.
so we have to find the adjacent side of right side.
By Pythagoras Theorem.
76.4² = c² + 39.3²
c² = 76.4² - 39.3²
c² = 4261.95
c = √4261.95
c = 65.3 feet

y = 2(x² + 15x + 100)
x² = x*x
100 ⇒ 1 x 100 ; 2 x 50 ; 4 x 25 ; 5 x 20 ; 10 x 10
200 = 2x² + 30x + 200
0 = 2x² + 30x + 200 - 200
0 = 2x² + 30x + 0
0 = 2(x² + 15x + ?)

Step-by-step explanation:
The figures are congruent, so all you need do is pick 1 point from each figure and tell what it does. I'm going to go from Figure J to figure K
I will pick the point (-4,8) on J. It is the furthest point upwards.
Where is that same point on K? It is at (2,4)
So what happened?
You've moved from -4 to 2 on the x value.
You've moved from 8 to 4 on the y value
You moved right (-4 to 2) = 6 units and
down (8 - 4) = 4 units
What would happen if you went from K to J
This time you have moved 6 units left and 4 units up.
Answer:
a translation left 6 units and up 4 units

Area of a semicircle: 1/2 (pi • r^2)
1/2(3.14 • 100)
1/2 ( 314 )
157
Triangle:
(6 • 8) ÷ 2

24
Add the area of the triangle & semicircle together: 157 + 24 = 181
Hope this helps! Have a great day!

Volume = B*h where B is the area of the base.
B= 4 * 10 = 40
V= 40 * 15
V= 600 cm^3
Your question has already provided the necessary information for us to be able to compute the volume. To find the volume of the triangular prism, you just need to multiply the area of the base (a triangle) by the height (15).
We already know how to find the area of a triangle.
5(4)
20 cm²
Now, multiply that by the height of the prism.
20 * 15 = 300 cm³
The volume of the triangular prism is 300 cm³.
