Answer:
x=18
Step-by-step explanation:
So (3x+20)° and (5x-16)° are angles that are vertically opposite to each other; which means that they are equal to one another. Which means we can say:
(3x+20)=(5x-16)
20+16=5x-3x
36=2x
x=18
*and the two angles are 74°
Answer:
Option C is the right answer.
Step-by-step explanation:
Given that:
Length of diagonal = 25 inches
Length of rectangle = 9 inches
Width of rectangle will be one of the two legs of right angled triangle and the diagonal will be the hypotenuse.
Using Pythagorean theorem;

Taking square root;

Therefore,
Option C is the right answer.
Answer:
f=

/4
y+
−1
/2
Step-by-step explanation:
Let's solve for f.
y=5x^0+4x−3
Step 1: Flip the equation.
4x+2=y
Step 2: Add -2 to both sides.
4x+2+−2=y+−2
4x=y−2
Step 3: Divide both sides by 4.
4x

Answer:
B
Step-by-step explanation:
The volume (V) of the triangular prism is calculated as
V = area of triangular face × length
Area of triangle =
bh ( b is the base and h the height )
Here b = 6 and h = 8, thus
Area =
× 6 × 8 = 3 × 8 = 24 units², thus
V = 24 × 20 = 480 units³ → B
48.7 rounded to one significant figure would be 50
