This is for the first one :) sorry I don’t have time to do the other two, but this will help with the other ones
Equation a^2 + b^2 = c^2
c = longest side, unknown
The answer is D.
12^2 + 10^2 = c^2
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.
The answer is B sorry i was wrong
Answer:
60 mins or 1 hour
Step-by-step explanation:
14 x 2 : 28 - 25 plus 25 is 50 min
38- 28 is 10
50 plus 10 is 60 min Or 1 hour
