Answer:
1. The measure of the remaining leg is 21\sqrt{3} units
2. The angle opposite the side with length 21 units measures 30°
Step-by-step explanation:
The Pythagorean theorem tells you the remaining side length is ...
√(42² -21²) = 21√3 . . . . . matches the first statement, discounts statements 3 and 5
The angle opposite the 21-unit leg can be found from ...
angle = arcsin(21/42) = 30° . . . . . matches the second statement, discounts statement 4.
Answer:
there could be 28 possible pairs because 57/2=28.5
Step-by-step explanation:
Answer:
the answer is 2880
Step-by-step explanation:
because you would use the formula (n - 2) x 180 which equals the sum interior angles of any polygon .
The letter n stands for number of sides so in this case you would do (18 - 2) x 180 so 16 × 180 = 2880
hope this helped :) pls ask if you need any more explanation .
pls give brainliest if you like my answer :)
I can't tell what it wants to say in the first part, but I'll do A and B for you.
Because all triangle angles add to 180 degrees, you know that angle PMU is 180-21+35 which is 124.
So a) is 124 degrees
And for b) you take the straight line and you know its 180 degrees. Knowing that angle UMP adds up to 180 degrees when added to PMU which is 124, then you subtract 180 - 124
So b) is 56 degrees.
Hope this helps
Also I can help you with the first 4 if I can see the question.
Answer: K = 44
Explanation:
K + 12 = 56
K = 56 - 12
K = 44
