Answer:
The measure of Angle A is 45.5 degrees
Step-by-step explanation:
In order to find the measure of the angle A, add it to the measures of angle B and C. Since it is an isosceles triangle, we know that B and C have the same measure. Then we set this equal to 180.
A + B + C = 180
2x + 4 + 3x + 5 + 3x + 5 = 180
8x + 14 = 180
8x = 166
x = 20.75
Now we can find the measure of Angle A by putting the value of x in for x.
2x + 4 = A
2(20.75) + 4 = A
41.5 + 4 = A
45.5 = A
y=5, x=7 because if 3x5=15 then 15-7=8 dont report me if i do get this wrong
Given the function:
f(x)=-x^2-5x+50
the zeros of the function will be obtained by factorizing the expression.
f(x)=-x^2-5x+50
f(x)=-(x^2+5x-50)
f(x)=-(x-5)(x+10)
the zeros are:
x=-10
x=5
hence taking the positive value for distance, we take x=5.
This represents the horizontal distance the diver jumped. Thus the correct answer is:
<span>x = 5; the diver hits the water 5 feet away horizontally from the board

Hhhhhhhhhhhhhhhhhhh the answer is 8
