5x+20=70 <br><br> solve for x

Anarel [89]

5x + 20 = 70
5x = 70 - 20
5x = 50
x = 50/5
x = 10

5(10) + 20 = 70
50 + 20 = 70
70 = 70

hope this helps :)

Please help!!!! Sine and cosine ratios

Kipish [7]

Answer: 40.9

Step-by-step explanation:

Given

angle given is $23^{\circ}$

$RC=16$

Using trigonometry

$\Rightarrow \sin 23^{\circ}=\dfrac{RC}{PC}\\\\\Rightarrow \sin 23^{\circ}=\dfrac{16}{X}\\\\\Rightarrow X=\dfrac{16}{\sin 23^{\circ}}\\\\\Rightarrow X=40.948\approx 40.9$

Using cosine formula

$\Rightarrow \cos 23^{\circ}=\dfrac{PR}{X}\\\\\Rightarrow PR=40.9\times \cos 23^{\circ}\\\Rightarrow PR=37.69\approx 37.7$
