Answer:
A = 60° , B = 30°
Step-by-step explanation:



To find the scientific notation of a number, place a decimal point after the first digit. Count how many places you moved the decimal point and that will be the power of 10.
19,340 = 1.9340×10^4
Think of a strategy that works out best for you.
Step-by-step explanation:
For a given rectangle,the area(A) is the product of its length and width
A=lw, given A=350m² and l=50m
transposing the equation for w gives w=A/l
w=350m²/50m=7m
That's it
2x + 3y = 23...........................(1)
3x - y = 7 Multiply by 3:-
9x - 3y = 21 Adding this to equation (1):-
11x = 44
x =
Plug this into equation (1):-
2(4) + 3y = 23
3y = 15
y = 5
Answer is x = 4, y = 5
