Answer:
x = 90°
y = 43°
Step-by-step explanation:
We know that one angle equals 47°.
The two triangles are right triangles, so that makes x = 90°.
To find y, we add 90 + 47.
That would give us 137°.
All triangles add up to 180°.
180 - 137 = 43.
43° is the answer.
If its a right-angled triangle you can find the third side if the length of the other 2 sides are known. Use the Pythagoras theorem.
If you have 2 triangles which are similar and you know the length of one or more sides of one of them then you can find the lengths of corresponding sides in the second triangle.
Answer:
16
Step-by-step explanation:
since he needs 32 points to get to 75 points,
soo you just dividi the points you need by the points you get by every question since it's 2 for every question you just need half of the question needed to get to 32 points soo divide it by 2 and the answer you get is 16.

Answer: The answer to the expression is 45.
Step-by-step explanation: You can simplify this expression using the order of operations:
46 - 2 x 4 + 7 first you have to do multiplication
46 - 8 + 7 then go from left to right
38 + 7 = 45 After doing so, you will arrive to your answer
