Answer:
four thousand three hundred and four
Step-by-step explanation:
Answer:
512
Step-by-step explanation:
1+1 = 2
2+2 = 4
4+4 = 8
8+8 = 16
16+16 = 32
32+32 = 64
64+64 = 128
128+128 = 256
256+256 = 512
they add the answer by itself. hope this helps
Answers:
- Angle A = 76
- Angle B = 37
- Angle C = 67
Triangle ABC is an acute triangle. It's also a scalene triangle.
====================================================
Work Shown:
x = measure of angle B
2x+2 = measure of angle A, since we're told its "2 more than twice angle B"
2x-7 = measure of angle C, for similar reasoning
The three angles add to 180. This is true for any triangle
A+B+C = 180
(2x+2)+(x)+(2x-7) = 180
5x-5 = 180
5x = 180+5
5x = 185
x = 185/5
x = 37
This means angle B is 37 degrees. The other two angles are
A = 2x+2 = 2*37+2 = 74+2 = 76
C = 2x-7 = 2*37-7 = 74-7 = 67
----------------
In summary, we have these three interior angles
As a way to check, note how A+B+C = 76+37+67 = 180. This confirms the answer. All three angles mentioned are smaller than 90 degrees, so this triangle is acute.
Furthermore, because all three angles are different measures, this means all three sides are different lengths. This leads to triangle ABC being scalene.
Answer
D
step 1
Memorize the formula, or look at the formula and solve it.
W = 2L / 3 and 2W + 2L = 50. Substitute 2L / 3 for W in the second equation to get:
<span>2(2L/3) + 2L = 50 </span>
<span>4L/3 + 6L/3 = 50 </span>
<span>10L/3 = 50 </span>
<span>L = 3 * 50 / 10 = 15. Replace L for 15 in the first equation: </span>
<span>W = 2(15) / 3 </span>
<span>W = 10</span>
