Answer:
x =
Step-by-step explanation:
According to Pythagorean Theorem, the square value of hypotenuse is equal to sum of square value of two legs:
x^2 + 4^2 = 10^2
x^2 + 16 = 100 subtract 16 from both side
x^2 = 84 find the root of both sides
x =
Answer:
Step-by-step explanation:
Answer:
f(2) = 10
Step-by-step explanation:
Simply just plug in 2 into the equation
f(2) = 3(2)² - 2
f(2) = 3(4) - 2
f(2) = 12 - 2
f(2) = 10
And we have our final answer!
The unknown angle would be 70.
Use the Pythagorean Theorem to solve this.
a2 + b2 = c2
Angle B plus Angle C equals 110.
180-110= 70.
