Answer:
Angle D equals 80 degrees.
Since both triangles and angles are congruent, you can use triangle ABC to find the measure of CDE.
ABC has to equal 180 degrees so that means that 30 + 70 + <B = 180
add: 100 + <B = 180
Subtract <B = 80
Angle B equals 80 degrees which also means that Angle D equals 80 degrees.
Answer:
the weight of 1 textbook is 2 pounds
the weight of 1 game is about 0.5 pounds
Step-by-step explanation:
1/2 of 2 = 0.5 pounds
0.5 times 8 (games) = 4
22 - 4 = 18
18 divided by 9 (textbooks) = 2 pounds
Y = sec(x) has a range that doesn’t include 0.

Let's start by listing each triangle and the measurements of all three angles. For each triangle, we've been given the measurements of 2 of the angles and the 3 angle will simply be 180 minus the other 2 angles. I assume you can do the subtraction, so I'll simply list each triangle with all three angle measurements.
NMO: 79, 22, 79
GHK: 79, 79, 22
PQR: 20, 79, 81
DEF: 82, 22, 76
And the triangles NMO and GHK are similar to each other since they have the same angles. The order really doesn't matter since it's OK for similar triangles to be rotated or reflected. The key thing to remember in a triangle is that if you've been told what 2 of the angles are, you also know what the 3rd angle is since the sum of the angles of a triangle will always be 180.
So the answer is:
