Answer:

≈ 56°

Step-by-step explanation:

Using the sine ratio in the right triangle

sin ? = $\frac{opposite}{hypotenuse}$ = $\frac{34}{41}$ , then

? = $sin^{-1}$ ( $\frac{34}{41}$ ) ≈ 56° ( to the nearest degree )

Use substitution to solve the system of equations.

(3.75, 5.5)

(Work is attached )
When using substitution , you substitute with a variable that is already by itself. In this case, the variable “y” is already by itself and equal to x+ 1.75 . you substitute that for the the y in the other equation and solve for the other variable which is “x”. After you solve for x , to find your y value, you have to substitute the x value in for either equation.

A circle has the circumference of 3.75 in. What is the diameter of the circle? (Use 3.14 for p. Round to the nearest tenth.) a.

HACTEHA [7]

Answer:

Step-by-step explanation:

The formula of a circumference:

$C=d\pi$

<em>d</em> - diameter

We have <em>C = 3.75 in</em><em>.</em>

Substitute:

$d\pi=3.75\qquad\text{use}\ \pi\approx3.14\\\\3.14d=3.75\qquad\text{divide both sides by 3.14}\\\\d=\dfrac{3.75}{3.14}\\\\d=\dfrac{375}{314}\\\\d\approx1.2\ in$
