The goal of any equation is to get the VARIABLE by itself on one side of the equation.
In both the figures we have a Right Angled Triangle.
Two sides of the right angled triangles are given and we are to find the Third side. This can be done using the Pythagoras Theorem, which states:
Hypotenuse² = Base² + Perpendicular²
For 1st figure, we have
Base = 21
Perpendicular = 20
So,
Hypotenuse² = 20² + 21² = 841
⇒
Hypotenuse = 29 (1st option is correct)
For 2nd Image, we have
Base= 6
Hypotenuse = 10
So, we can write:
10² = 6² + Perpendicular²
Perpendicular² = 64
⇒
Perpendicular = 8 (Option Fourth)
Answer:
-5x - 1
Step-by-step explanation:
Step 1: Write expression
(-6x + 2) + (x - 3)
Step 2: Combine like terms
-5x - 1
A) after 5 years she will pay $7,200
b) she will save $2880
Answer:
O 16,30,34
Step-by-step explanation:
To confirm, use Pythagorean theorem to check.
(16)² + (30)² = (34)²
256 + 900 = 1156
=> It is correct
=> Therefore, this set of three lengths will form a right triangle
