Answer:
m∠Q = 121°
m∠R = 58°
m∠S = 123°
m∠T = 58°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Create an expression for the sum of all the angles and equate it to 360, then solve for x:
∠Q + ∠T + ∠S + ∠R = 360
⇒ 2x + 5 + x + 2x + 7 + x = 360
⇒ 6x + 12 = 360
⇒ 6x = 360 - 12 = 348
⇒ x = 348 ÷ 6 = 58
So now we know that x = 58, we can calculate all the angles:
m∠Q = 2x + 5 = (2 x 58) + 5 = 121°
m∠R = x = 58°
m∠S = 2x + 7 = (2 x 58) + 7 = 123°
m∠T = x = 58°
Answer:
the third side could be 8 or 2
Step-by-step explanation:
Answer:
90,000,000
Step-by-step explanation:
If it is to hard for you, you can:
-Multiply the first digits by each other. 1 x 9 = 9.
-Then, add up all the zeros. In this case, there are, 7 zeros.
-Then, combine the 9 and add the seven zeros to make it:
90,000,000.
0.25 ft equals 0.083 yd (0.25/3 ft per yd)
4 ft equals 1.33 yd
200 ft equals 66.6 yd
0.083 x 1.33 x 66.6 = 7.35 cubic yards
