Answer:
16
Step-by-step explanation:
To calculate x we must use the trig function of tangent:
as tangent is opposite divides by adjacent we can get this equation:
which is equal to:
So x must equal to 15.588.. (just put the second bit in the calculator
As all the values provided are integers you round this to the nearest whole number:
16 (as the third digit, 5, rounds up)
so our answer is 16
Answer:
495
Step-by-step explanation:
1,650 x 0.7 = 1,155

Hope this helps!
Well, first since i split this up into 3 shapes. Then I multiplied 4x8 which was 32 and since there were two,it would be another 32. Then I multiplied 12x4 which was 48. Then I added 32+32+48 which equaled 112 square feet.
Answer:
y=5 or y=−5 it does not matter either one
Step-by-step explanation:
25=y2
Step 1: Subtract y^2 from both sides.
25−y2=y2−y2
−y2+25=0
Step 2: Subtract 25 from both sides.
−y2+25−25=0−25
−y2=−25
Step 3: Divide both sides by -1.
−y2
−1
=
−25
−1
y2=25
Step 4: Take square root.
y=±√25
y=5 or y=−5
