X=14
every triangle equals 180 when adding all the angles together 72+36 = 108 So 180-108 = 72 (also note this is an isosceles triangle)
Now 72-16 = 56
56÷4 = 14
Answer:
y = 2x + 1
Step-by-step explanation:
The gradient of line A is
Parallel lines have the same gradient, so m = 2.
Substituting the coordinates of P into y = mx + c,
Given:
Right triangle with one angle 45°
To find:
The value of q and r.
Solution:
Opposite to θ = 16
Adjacent to θ = r
Hypotenuse = q
Using trigonometric ratio formula:
The value of tan 45° = 1
Do cross multiplication, we get
r = 16
Using trigonometric ratio formula:
The value of sin 45° = .
Do cross multiplication, we get
The value of r is 16 and the value of q is .
Answer:
Store A
Step-by-step explanation:
A) The price per scoop is the slope, or 0.75 dollars, or 75 cents.
B) The slope is y2 - y1 / x2 - x1. Plugging in the values, we get 8-8 / 3-3 = 1. Therefore, the price per scoop is 1 dollar.
C) Two points on the graph are (2,3) and (4,6). Their slope is (6 - 3) / (4 - 2) = 3/2 = 1.5. The price peer scoop is 1.5 dollars.
The cheapest ice cream per scoop is Store A.
