Answer:
a) x = 2, y = 1
b) x = 9, y = -9
Step-by-step explanation:
a) 
⇒ 
⇒ 
and
⇒ 
⇒ 
By solving the above two equations, we get;
x = 2 and y = 1
b) 
⇒ 
⇒ 
and
⇒ 
⇒ 
By solving the above two equations, we get;
x = 9 and y = -9
True. The only area where a line parallel to one side would be able to intersect both other sides would be in a place that proportionally divides the other sides.
Let x = big number
Let y = small number
x + y = 66...Equation A
2y = x + 15...Equation B
We have two equations in two unknowns.
x + x + 15 = 66
2x = 66 - 15
2x = 54
x = 54/2
x = 27
Plug x = 27 into EITHER equation above to find y.
I will use Equation A.
x + y = 66
27 + y = 66
y = 66 - 27
y = 39
The two numbers are 27 and 39.
Answer:
The measure of angle A is 115°
Step-by-step explanation:
we know that
The sum of the internal angles of a triangle must be equal to 180 degrees
so
∠C+∠A+∠B=180°
substitute values and solve for x
x°+(3x-35)°+(x-35)°=180°
5x°=180°+70°
x=250°/5=50°
Find the measure of angle A
∠A=(3x-35)°
substitute the value of x
∠A=(3(50)-35)=115°
