Otrada [13]2 years ago
3 0

Answer:

  • 40. C. 40
  • 41. B. ∠ACE ≅ ∠ECB

Step-by-step explanation:

<h3>#40</h3>

The triangle with angle x is isosceles as two sides marked as same.

The two angles opposite to equal sides measure x.

<u>Sum of interior angles of the triangle is:</u>

  • 100 + 2*x = 180
  • 2x = 180 - 100
  • 2x = 80
  • x = 40
<h3>#41</h3>

Common angle of the two triangles is angle C.

Correct choice is B

Hello,

If you are starting with the angle of 40 degrees, you have an adjacent side and hypotenuse. Therefore, it is a cosine relationship.

We can write:

cos(40) = adj / hyp
cos(40) = x / 220

To solve for x, simply multiply 220 by the cos(40).
You can write it as:  220 cos(40)

Good luck,
MrEQ

Evaluate x³ for x=2.
loris [4]

Answer:

8

Step-by-step explanation:

If we have anything to the third power, we are multiplying the number by itself 3 times.

If x = 2, then the expression is 2^3.

2\cdot2\cdot2=8

Can someone help me with this problem?
pashok25 [27]
No, it is not a solution.

Let's plug 5 into the equation where p is.

10(5) - 2 > 97

50 - 2 > 97

48 > 97

This is false, 48 is less than 97.
