The score of Raven is 9 points
<em><u>Solution:</u></em>
Let the point scored by bangal be"x"
Score of Raven = 40 points
Given that,
The ravens scored 13 more than three times number points that the bangals scored in their last game
Score of raven = 13 + 3(score of bangal)
40 = 13 + 3x
Solve the above equation for x
3x = 40 - 13
3x = 27
x = 9
Thus the score of Raven is 9 points
Step-by-step explanation:
= 5 • ( 4• x )
= 5 ( 4x )
= 20x
Hey there!
A quadrilateral has 360 degrees. So add all the degrees together to 360. 9x+1+5x-12+8x+61+90=360. 90 degrees is in the bottom left corner. Combine like terms. 22x+140=360. Subtract 140 from each side. 22x=220. Divide 22 on each side to get x=10. Plug in 10 for x in angle D. 5(10)-12=38. The measure of angle D is 38 degrees.
I hope this helps!
Answer:
SA = 2520 ft^2
Step-by-step explanation:
a = 21ft
b = 29ft
c = 20ft
h = 30ft
SA = 2
+ (a+b+c)h
= s(s﹣a)(s﹣b)(s﹣c)
s = 
SA= ah + bh + ch + 
SA= (21 * 30) + (29 * 30) + (20 * 30) +
SA = 2520 ft^2
