Answer:
x = 9
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° =
, then
sin45° =
=
=
( cross- multiply )
x ×
= 9
( divide both sides by
)
x = 9
Answer=A
Let's write the an equation in slope intercept for for the line.
y-intercept=10
slope=rise/run=15/2=7.5
equation:
y=mx+b
y=7.5x+10
Solve for x=7
y=7.5(7)+10
y=52.5+10
y=62.5
Answer=A
Answer:
The answer to your question is 757.1 cm²
Step-by-step explanation:
Data
Ratio 1: 1.618
long side = 35 cm
Area = ?
Process
1.- Use proportions to solve this problem
1 : 1.618 :: x : 35
x = (35 x 1) / 1.618
x = 35 / 1.618
x = 21.63
2.- Calculate the area of the rectangle
Area = base x height
Area = 35 x 21.63
Area = 757.1 cm²
