It is 348000 because if its 5 or above it rounds up and 4 or below rounds down so the 5 rounds the 7 to an 8
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:
9 arms
Step-by-step explanation:
6 eyes = 2 eyes three times (3 x 2), so three arms 3 times (3 x 3) = 9
For every hour. It will leak a half of cup (1/2). If 30 mins= 1/4 of a cup. Times it but two. 60 or 1 hour = 2/4 or simplified 1/2
