Answer:
y=12°
x= 20°
Step-by-step explanation:
5y=60
y=60/5=12
3x+60+60=180
3x=180-120=60
x=60/3=20

Answer:
The time will be 10:42:40 am. = 10:42 am.
Step-by-step explanation:
∵ The time of 10 questions = 10 × 30 = 300 sec. ÷ 60 = 5 min.
∵ The time of 15 questions = 15 × 40 = 600 sec. ÷ 60 = 10 min.
∵ The time of 12 questions = 12 × 2 = 24 min.
∵ The total of the questions = 10 + 15 + 12 = 37
∵ The time of total rests between the questions = 36 × 5 = 180 ÷ 60 = 3 min.
* Note: (The rests time less than the number of questions by 1 because there is no rest after the last question)
∵ The time of sharpens = 2 × 20 = 40 sec. ÷ 60 = min.
∴The total time of the test = 5 + 10 + 24 + 3 + = min.
Answer:
(8, 2 )
Step-by-step explanation:
Given the 2 equations
x + 4y = 16 → (1)
- x + 3y = - 2 → (2)
Adding the 2 equations term by term will eliminate the x- term
0 + 7y = 14
7y = 14 ( divide both sides by 7 )
y = 2
Substitute y = 2 into either of the 2 equations and solve for x
Substituting into (1)
x + 4(2) = 16
x + 8 = 16 ( subtract 8 from both sides )
x = 8
solution is (8, 2 )
Answer:
Vertical angles
Step-by-step explanation:
The diagram shows two straight line intersecting to form vertical angles. One of such pair of vertical angles formed is <1 and <2.
Vertical angles are congruent to each other. Therefore, the reason why <1 ≅ <2 is because they are vertical angles or vertical angles pair.
