350.03 thats the answer the y might be a variable
Every triangle has an angle measure of 180 degrees.
so 42+20+x (where x is the measure of the third angle)=180
Combine like terms.
62+x=180
Subtract 62 from both sides
x=118.
Answer:
-6x
Step-by-step explanation:
=8+(−2)(3x)+(−2)(4)
=8+−6x+−8
Combine Like Terms:
=8+−6x+−8
=(−6x)+(8+−8)
=−6x
Answer:
x = 10
Step-by-step explanation:
note that sin30° = 
Since the triangle is right use the sine ratio to find x
sin30° = 
= 
multiply both sides by x
x × = 5 ( multiply both sides by 2 )
x = 10
