Answer:
82 units
Step-by-step explanation:
From the image, we can see that the 2 triangles are similar triangles.
Thus:
BC = EF
BD = EG
CD = FG
Now, BD = 4x - 9 and EG = 2x + 15
Thus;
4x - 9 = 2x + 15
4x - 2x = 15 + 9
2x = 24
x = 24/2
x = 12
Thus, in triangle EFG where EG = 2x + 15, then EG = 2(12) + 15 = 39
Also, EF = BC = 17
FG = 26
Thus, perimeter of triangle EFG is;
P = 26 + 17 + 39
P = 82 units
M∠A+ m∠B+<span>m∠C = 180
</span>2x + 8 + 2x - 2+<span>3x - 8 = 180
7x - 2 = 180
7x = 180 +2
7x = 182
x = 182/7
x=26
</span><span>m∠A = (2x + 8)° = 2(26) + 8 =60
</span><span>m∠B = (2x - 2)° = 2(26) -2 =50
</span><span>m∠C = (3x - 8)° = 3(26) - 8 =70
</span>
answer :
<span>measure of the largest angle is m<C = 70</span>
Answer:
6-4 = 2 4-4= 0 and 2/2 = 1
So.. Y=1 !
But if you're looking for the slope, and the Y- intercept, which I think you are, then your slope will be 6, and the y-Intercept would be (0,4).
B) the internal volume of a tank
1 x 90 x 20 = ?
V = ?
Answer:
684 π
Step-by-step explanation:
volume of a sphere = (4/3) x (n) x (r^3)
n = 22/7
r = radius
volume of larger sphere
4/3 x n x 9³ = 972 n
4/3 x n x 6³ =288n
972n - 288n = 684n
