Answer:
Step-by-step explanation:
As for the angles of both triangles; they’re the same. The sides are 1:2.
I’m giving you formulas that are labeled: side a shortest
” b mid length
” c hypotenuse
angle α(alpha) opposite side a
” β(beta) ” ” b
” γ(gamma) ” ” c
A major formula for rt triangles is: a^2+b^2=c^2.
*Another is: a/sinα=b/sinβ=c/sinγ.
Remember α+β+γ=180°.
As for sides a&b use the above formula.
As for <ACB; the angle is γ which is a rt <.
Given: tan<x=5/2+1/2=6/2=3atan=71.565……….°=β. So α=18.44…….°. γ= rt angle.
To get the sides use the formulas at *.

Step-by-step explanation:
The surface area of the cube is 64 cm².
<h3 /><h3>What is volume?</h3>
Volume is the amount of space that is enclosed within a container.
To calculate the surface area of the cube, we use the relation below.
Formula:
- A = 6V
............ Equation 1
Where:
- A = Surface area of the cube
- V = Volume of the cube.
From the question,
Given:
Substitute this value into equation 1
- A = 6(35)
- A = 6(10.6999)
- A = 64.2
- A = 64 cm²
Hence, The surface area of the cube is 64 cm².
