Answer:

x = 25

Step-by-step explanation:

Looking at the triangle we know that it is a right triangleor a 90⁰ triangle.

(2x + 15)⁰ + x⁰ = 90⁰

2x + 15⁰ + x⁰ = 90⁰

<u>2x + x</u> + 15⁰ = 90⁰

3x + 15⁰ = 90⁰

3x <u>+ 15⁰ - 15⁰</u> = <u>90⁰ - 15⁰</u>

3x = 75⁰

<u>3x / 3</u> = <u>75⁰ / 3</u>

x = 25⁰

Now plug the x value in the missing angles.

2x + 15⁰

<u>2(25⁰)</u> + 15⁰

<u>50</u><u>⁰</u><u> </u><u>+</u><u> </u><u>15</u><u>⁰</u>

65⁰

According to the sum of triangle, all angles add up to 180⁰. Even though this is a right triangle, it should add up 180⁰ in order to be a triangle.

65⁰ + 25⁰ + 90⁰ = 180⁰

Hope this helps and stay safe, happy, and healthy, thank you :) !!

Q4, 4y²=60
y=√15 ( i am not sure)
q6, (5+y) ²=81
5+y=9
y=4
q7 (x+4) (x) =77
x²+4x-77=0
(x+11) (x-7) =0
x=-11(rej) or x=7
