Answer:
x=56
Step-by-step explanation:
There are 3 angles in the triangle
x, 60 and the unknown angle we will call y
y and 2x+4 make a straight line, so that adds to 180
y + 2x+4 = 180
Solve for y
y = 180 - (2x+4)
y = 180 -2x-4
y = 176 -2x
The three angles in a triangle add to 180
x + 60 + y = 180
Substitute in for y
x + 60 + 176 -2x = 180
Combine like terms
-x +236 = 180
Subtract 236 from each side
-x+236-236 = 180-236
-x = -56
Multiply by -1
x = 56
Answer:
Step-by-step explanation:
2x+5= -25 .........(1)
and -3m-6= 40........(2)
Considering (1): 2x+5= -25
2x = -25 - 5
2x = -30
x = -30/2
x = -15
Considering (2): -3m-6= 40
-3m = 40 + 6
-3m = 46
m = -46/3
Product of x and m = (-15) × (-46/3)
= -5 × -46
= 230

I'm tryna figure out the same question
Answer:
Y = 21 when x=18
X varies 3 numbers subtracted from Y so now it comes as x= 18 then y is plus 3 the the number shown on x which is 18+3 then you get 21.
