I think it’s 2. You can see this because if you count the squares in the smaller triangle it is 3 along. You would then need to double the amount of squares on all sides. This makes the larger triangle now 6 squares along. 6/3 is 2 making the scale factor 2. (This is only if I have read the question correctly and we are calculating small to big. If I have read it wrong and it is big to small it would be 1/2)
Answer:
<h3>∴∠B=30°</h3>
Step-by-step explanation:
Complementary:
Two angles is said to complementary when the sum of two angles is 90 degree.
Given that,
∠A and ∠B are complementary.
Then, ∠A + ∠B = 90°
Cos A = 0.5
![\Rightarrow A=cos^{-1}(0.5)](https://tex.z-dn.net/?f=%5CRightarrow%20A%3Dcos%5E%7B-1%7D%280.5%29)
![\Rightarrow A=cos^{-1}(cos \ 60^\circ)](https://tex.z-dn.net/?f=%5CRightarrow%20A%3Dcos%5E%7B-1%7D%28cos%20%5C%2060%5E%5Ccirc%29)
![\Rightarrow A=60^\circ](https://tex.z-dn.net/?f=%5CRightarrow%20A%3D60%5E%5Ccirc)
Since
∠A + ∠B = 90°
⇒ 60°+ ∠B = 90° [ plug ∠A= 60°]
⇒∠B=90°-60°
⇒∠B=30°
<h3>∴∠B=30°</h3>

Answer:
Step-by-step explanation:
c is the number of cloth gloves sold.
r is the number of cloth gloves sold.
c + r =127
c = 127 - r
6.95c + 8.95r = 1070.65
6.95(127 - r) + 8.95r = 1070.65
882.65 + 2r = 1070.65
r = 94
c = 33
-1/3 + (-5/6) + (-7/3)
-(1/3 + 5/6) + (-7/3) : equivalent
-5/6 + (-1/3) + (-7/3) : equivalent
-1/3 - (5/6 - 7/3) : not equivalent
-1/3 + (-7/3) +(-5/6) : equivalent
