Answer:
18.03 cm
Step-by-step explanation:
The two sides of the rectangle are the legs of a right triangle and the diagonal is the hypotenuse. We can use the Pythagorean theorem
a^2 + b^2 = c^2
10^2 +15^2 = c^2
100 +225 = c^2
325 = c^2
Take the square root of each side
sqrt(325) = sqrt(c^2)
18.02775638 =c
Rounding to the nearest hundredth
18.03 =c
It is 29 because a right angle is 90 so the equation should be 61 plus x=90 so you could just subtract and it would be 29
Answer:
a = 6
Step-by-step explanation:
-6(2 + a) = -48
it is basically 2 steps
Divide by -6 first
(2 + a) = -48 / -6
2 + a = 8
minus the 2
a =6
