Answer:
x=1.94
x = - 1.94
Step-by-step explanation:
8x² + 5 = 35
Subtract 5 from each side
8x² + 5-5 = 35-5
8x² = 30
Divide each side by 8
8x² /8 = 30/8
x² = 15/4
Take the square root of each side
sqrt( x²) = ±sqrt(15/4)
x = ±sqrt(15/4)
x=1.93649
x = - 1.93649
To the nearest hundredth
x=1.94
x = - 1.94

<u>Answer:</u></h2>
'?' is <u>88°.</u>
<h2>
<u>Step-by-step explanation:</u></h2>
- First, we work out the final angle of the left triangle, which has a total of 180°. To do this we take 40° and 66° from 180°, giving us <u>72°</u>
- Because there is a straight line along the bottom (which will total 180°), we take both 72° and 56° from 180°, giving us <u>52°</u>, which is the bottom left angle of the right triangle.
- Finally, to work out '?', we take 52° and 40° from 180° to get our final answer of <u>88°.</u>
