Gabrielle's age is 3x (in which x is mikhail's age)
the sum is 56 so 3x+x=56
3x+x=56
4x=56
x=14
since x was mikhail's age, mikhail is 14 years old
Answer:
a. 1 hour and 32 minutes b. 8:07
Step-by-step explanation:
a.8:34-7:02
b. 9 minutes +1 hour and 32 minutes+12 minutes=1.53 hours before 10=8:07
Answer:
see explanation
Step-by-step explanation:
The opposite angles of an inscribed quadrilateral are supplementary, thus
5x + 20 + 7x - 8 = 180
12x + 12 = 180 ( subtract 12 from both sides )
12x = 168 ( divide both sides by 12 )
x = 14
Thus
∠ RQP = 10x = 10(14) = 140°
∠PSR = 180° - 140° = 40° ( opposite angles are supplementary )
∠ SRQ = 7X - 8 = 7(14) - 8 = 98 - 8 = 90°
∠ QPS = 5x + 20 = 5(14) + 20 = 70 + 20 = 90°
