Can someone me with these 2 questions i’m stuck and need and this is really important.

answer:

question 4: 30 inches

question 5: 15 inches.

step-by-step explanation:

q4: use pythagorean theorem. +=. . 900=. take the square root of both sides and you get that c=30.

q5: multiply 5 by 2 to get hypotenuse. hypotenuse = 10then use pythagorean theorem to get the length of the longer leg. (5)^2+=(10)^2. (10)^2 -(5)^2=225. =225. take square root of both sides and you get the length of longer leg to be 15 inches.

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
