88 degrees is the answer. You would start by setting up the equation as (5x+7)+(8x+8)+(3x+5)=180 because all angles of a triangle have a sum of 180 degrees. From there you combine like terms which would leave the answer of being 16x+20=180 then you subtract the 20 from 180 to get x by itself. Then that would leave you with 16x=160 then you divide both sides by 16 to get x=10. From there you plug 16 into the x in the planetarium equation which is 8(10)+8 which equals 88 degrees
The answer:
-7 3/4, -7.6, -6 7/8, 32/5, 6.9
Answer:
27
Step-by-step explanation:
30% of 90 can be written as 30% × 90
= 30/100 × 90
= 27

Gimmie brainliest plzzz <3
To answer the question above, substitute the values of the variables x, y and z given to the equation.
2x² - 2(z^4)y² - x²(z^4)
2(-4)² -2(2^2)(3²) - (-4)²(2^4) = -296
Thus, the numerical answer to the question above is -296.
