Angles on a straight line add up to 180 degrees.
180-100 = 80
x + 3x = 4x
80/4 = 20
x = 20 degrees
Answer:
Uh 90 i hope your kidding
Step-by-step explanation:
Answer:
A = 33.33
Step-by-step explanation:
P = 0.006A^2 - 0.02A + 120
*** P = 126 ***
126 = 0.006A^2 - 0.02A + 120
126 = (3/500)A^2 - (1/50)A + 120
*** multiplied with 500 on both sides ***
63000 = 3A^2 - 10A + 60000
63000 - 3A^2 + 10A - 60000 = 0
3000 - 3A^2 + 10A = 0
3A^2 - 10A - 3000 = 0
3A^2 + 90A - 100A - 3000 = 0
3A(A + 30) - 100(A + 30) = 0
(A + 30)(3A - 100) = 0
A + 30 = 0 | 3A - 100 = 0
A = -30 | 3A = 100
A = -30 | A = 100/3
Human age cannot be negative so
A = 100/3 = 33.33
Answer:
The hypotenuse is square root of 65
Step-by-step explanation:
a^2 + b^2 = c^2
legs of the right triangle are a and b. Just substitute 4 for a and 7 for b and solve.
4^2+7^2=16+49=65
c^2=65
Find the square root of both sides to get
c=the square root of 65
Yes it does because in order to find out if a triangle is a right triangle, you can use the Pythagorean theorem.
sqrr 2 squared + sqrr 2 squared= 2 squared
simplify this:
2+2=4
because the equation is correct, this can make a right triangle
