The two triangles are similar and equal therefore; It means the corresponding sides are equal and the corresponding angles are equal. Hence;
ZX=EF, thus,ZX = 1.3 in.
EG = XY, thus, EG = 3.0 in.
m∠ X = m∠E, thus m ∠X = 48°
m∠ G = m∠Y, and angles in a triangle add up to 180 thus;
m ∠ G=180- (107 +48) = 25°
Answer:
n = -13
Step-by-step explanation:
19 + 10n = 7n - 20
Subtract 7n from each side
19 + 10n-7n = 7n-7n - 20
19+3n = -20
Subtract 19 from each side
19+3n -19 = -20-19
3n = -39
Divide each side by 3
3n/3 = -39/3
n = -13
Answer:
-4,2
Step-by-step explanation:
(x-2) (x+4)=0
x-2=0
x=2
x+4=0
x= -4
Just use a simple way by adding the gas used and left to get 13.5 gallons which is 3/4 tank than divide that by 3 which is 4.5 so 4.5 is a 1/4 tank and times that by 4 the Answer is 18 gallons
<span> y = x</span>² <span>+ 3x - 10
a=1 b=3 c=-10
x = -b/2a = -3/2 = -1.5
y = (-1.5)</span>² + 3(-1.5) - 10 = 2.25 - 4.5 - 10 = - 12.25
(-1.5, -12.25) ← <span>vertex of the parabola</span>
