Answer:
x = 7
Step-by-step explanation:
Let
x = the unknown number
double it :
2x
add 11:
2x + 11
I get 25:
The equation is
2x + 11 = 25
2x = 25 - 12
2x = 14
Divide both sides by 2
x = 14/2
x = 7
Answer:
(-2,-1)
Step-by-step explanation:
Finding the x coordinate:
(-5) + 1 = (-4)
-4 / 2 = -2
Finding the y coordinate:
(-3) + 1 = (-2)
(-2) / 2 = -1
Answer:
366.6 mm²
Step-by-step explanation:
Step 1: find XY using the Law of sines.
Thus,

m < W = 180 - (70+43) (sum of angles in a triangle)
W = 180 - 113 = 67°
WY = 24 mm
X = 43°
XY = ?

Cross multiply:


Divide both sides by 0.68 to solve for XY


XY ≈ 32.5 mm
Step 2: find the area using the formula, ½*XY*WY*sin(Y).
Area = ½*32.5*24*sin(70)
Area = ½*32.5*24*0.94
= 32.5*12*0.94
Area = 366.6 mm² (nearest tenth)
