Answer:
∠ABD = 45°
Step-by-step explanation:
Since ABCD is a square, its diagonals (Line BD) bisect the angles of the corners of the square (∠ABC) into two equal angles (∠ABD and ∠CBD). The angle of each corner is 90° so you can find ∠ABD.
2(∠ABD) = 90°
∠ABD = 90° ÷ 2
∠ABD = 45°
Answer:
x = 106
Step-by-step explanation:
The angle with a measure of 106 degrees and the angle labeled "x" are opposite exterior angles
Opposite exterior angles are congruent
Hence, x = 106
To solve this we will use inverse operations.
The inverse operations for subtraction is addition.
y - 10 = 32
32 + 10 = 42
So, y = 42 BUT lets check our work.
42 - 10 = 32.
So y = 42.
The rule for rounding is to go the nearest number. If the numbers you are trying to round is less than 5, then round down. If it is equal to or more than 5, round up. for these two numbers we would round down for both. when we add them we get 317+82=399
