Answer:
The answer will be D!
Step-by-step explanation:
First, let's find the value of X:
2x + 4x + 3x = 81
9x = 81
x = 9
Then, multiply it by the biggest side which is 4:
9 x 4 = 36
Answer:
45 degrees
Step-by-step explanation:
360 degrees is a whole circle, and there are 8 slots
360 / 8 = 45
Answer:
Step-by-step explanation:
Rectangle:
length = l = 12 cm
Width = w = 0.8 cm
Use Pythagorean theorem to find the diagonal
Diagonal² = l² + w²
= 12² + 0.8²
= 144 + 0.64
= 144.64
Diagonal = √144.64 = 12.03 cm
Diagonal of square = diagonal of rectangle
= 12.03 cm
To find the side of square again use Pythagorean theorem,
side² + side² = 12.03²
2 sides² = 144.64
side² = 144.64/2
side² = 72.32
side = √72.32
Side = 8.50 cm
Answer:
The equation of the line in standard form is
Step-by-step explanation:
The equation of the line in point slope form is
we have
so
step 2
Find the equation of the line in standard form
The equation of the line in standard form is
where
A is positive integer
B and C are integers
we have
Multiply by 4 both sides to remove the fraction
Step-by-step explanation:
Ok, so we kno that
A + B = 90
we also know that
A - B = 20
There are a lot of ways to solve this, but I think elimination will be best
A + B = 90
+ (A - B = 20)
-----------------------
2A = 110
A = 55
Therefore,
B = 90 - 55 = 35
