Angle B is the linear pairs with 60°, so the size is 180-60=120°
Angle ABC is the linear pair with 120°, so the size is 180-120-60°
Angle A corresponds to angle 60°, so they are equal
Angle BAC is the linear pair with angle A and angle 70°, so 180-(60+70)=50°
Angle ACB is 180-(50+60) = 70°

Given :-
- Time = 5 hours
- Speed = 120 km/h
To find:
We know:-
- Distance = Speed × Time
- Distance = 5 × 120
- Distance = 600km
Required Answer :-
600 km

The value of the expression will be equal to 145.
<h3>What is an expression?</h3>
The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that make an expression for divide 50 by half and add 20 and multiply by 2.
The expression will be solved as below,
E = 50/2 + 25 x 2 + 50 + 20
Solve the above expression by PEMDAS,
E = 25 + 50 + 70
E = 145

Answer:
operator
Step-by-step explanation:
Operator is represented as any symbol that indicates an operation to be performed.
Examples:
- Square root of√x, which indicates the square root is to be taken
- d/dx, which indicates differentiation with respect to x is to be performed
