4=\frac{t}{2.5}
To solve multiply both sides by 2.5 ( to cancel out the fraction )
10=t
t=10

So you need to move the 2.5 from one side of the equation to the other so you multiply it across.
4 * 2.5 = t 
10 = t

In ΔDEF, the measure of ∠F=90°, FD = 63 feet, and DE = 71 feet. Find the measure of ∠E to the nearest degree.
stepan [7]

Answer:

Step-by-step explanation:

∠F=90°, FD = 63 feet, and DE = 71 feet.

That's a right angle triangle also.

measure of ∠E to the nearest degree

sin∠E = 63/71

sin∠E = 0.8873

∠E= sin^-1 0.8873

∠E= 62.5°

Based on the coordinates of triangle RST, we can infer that triangle RST is <u>not a right-angled triangle. </u>

<h3>Is triangle RST a right-angled triangle?</h3>

For this to be a right-angled triangle, the Pythagoras theorem has to apply where:

Largest side² = Side A² + Side B²

Lengths of the triangle:

RS² = (4 - 2)² + (4 - 3)²

= 5

ST² = (5 - 4)² + (0 - 9)²

= 17

TR² = (2 - 5)² + (3 - 0)²

= 18

We can see that:

18 ≠ 17 + 5

This is therefore not a right-angled triangle.
