Answer:
x=12
Step-by-step explanation:
Since the triangle is isosceles, the 2 base angles are congruent.
Also, the interior angles of a triangle add up to 180.
32+7x-10+7x-10=180.
Solve.
14x+32-20=180
14x+12=180
14x=168
<u>x=12</u>

Answer:
<u>Bob and John can finish the job together in approximately 2.92 hours or 2 hours and 55 minutes</u>
Step-by-step explanation:
Let's recall that the formula for solving this kind of problems is:
T/A + T/B = 1, where T = time working together, A = the time for person A working alone, and B = the time for person B working alone.
Now, replacing with the values we have:
T/5 + T/7 = 1
35 is the Lowest Common Multiple of 5 and 7
5T + 7T = 35
12T = 35
T = 35/12
T = 2.92 (Rounding to the next hundredth) and 0.92 * 60 ≅ 55
T ≅ 2.92 hours (Around 2 two hours and 55 minutes)
