Answer: B
Step-by-step explanation:
The only labeled angle is 111
We can conclude that angle 3 is also 111
1 and 2 are both less than 90
Therefore, 1 is 69, 2 is 69, and 3 is 111

Answer/Step-by-step explanation:
In mathematics, there's an order to follow in solving calculations like the problems given above. The acronym, PEDMAS illustrates or makes us remember which order to follow. The acronym stands for:
P - Parenthesis. Given any problem to solve, first, solve any operation within a parenthesis. That is, expressions that are grouped together.
E - Exponents. Next in line of priority order is to solve expressions involving exponents.
D - Division
M - Multiplication
A - Addition, and
S - Subtraction.
Now, solve each expression given in the correct order of operation using PEDMAS:
10 - 3³ ÷ 9
10 - 27 ÷ 9
10 - 3
= 7 (the order of operation is EDS = Exponent, Division, and lastly, Subtraction)
7² ÷ (4 + 3)
7² ÷ 7
49 ÷ 7
= 7 (order of operation = PED)
7 × 5 - 2²
7 × 5 - 4
35 - 4
= 31 (EMS)
(6 + 2²) × 10
(6 + 4) × 10
10 × 10
= 100 (PM)
3 × 6 + 8²
3 × 6 + 64
18 + 64
= 82 (EMA)
4³ - 10 ÷ 5
64 - 10 ÷ 5
64 - 2
= 32 (EDS)
3² × 2 - 9
9 × 2 - 9
18 - 9
= 9 (EMS)
9 × 3² - 8
9 × 9 - 8
81 - 8
= 73 (EMS)
6² ÷ 3 - 5
36 ÷ 3 - 5
12 - 5
= 7 (EDS)
(9 - 5)² ÷ 4
(4)² ÷ 4
16 ÷ 4
= 4 (PED)
