Answer:
x = 18.25
x = 60.
Step-by-step explanation:
Top question w/ the triangle. All triangles must equal 180 degrees (or else it's not a triangle or more than 1 triangle; which if you take Trig, you will encounter).
Knowing that all triangles are equal to 180, you can add all the angles given and set it equal to 180 to solve for x.
[tex]35+70+(4x+2)=180\\x = 18.25[/tex]
If the question above asks for the value of x, the answer is 18.25.
Second question, these two angles MUST equal 180 degrees. Therefore, we can add the two angles and set it equal to 180 and solve for x.
[tex]x+2x=180\\3x=180\\x=60[/tex]
If the question asks for the value of x, the answer is 60.
If the question asks for the missing side or the side with x, MAKE SURE YOU REPLACE X WITH IT'S NUMERICAL VALUE!!!
