Answer:
x=28
Step-by-step explanation:
We can use similar triangles and proportions to solve this problem. Put the side of the small triangle over the same side of the larger triangle.
x 42
---------- = ----------
x+10 42+15
Simplify
x 42
---------- = ----------
x+10 57
Using cross products
57x = 42 (x+10)
Distribute
57x = 42x+420
Subtract 42x from each side
57x-42x = 42x-42x +420
15x = 420
Divide each side by 15
15x/15 = 420/15
x=28
Answer:
Step-by-step explanation:
Given
See attachment for graph
Required
The line graph
First, consider the following points on the graph.
First, calculate the slope.
undefined
Since, the slope is undefined; we simply consider only the value of x.
The line equation is:
Area of triangle = 1/2 ABsinC
Since all sides are equal, it means it is an equilateral triangle
⇒All angles are 60°
Area of triangle = 1/2 ABsinC
Area of triangle = 1/2 (3.5)(3.5)sin(60°)
Area of triangle = 5.3 in²
Answer:
-1, -2, -3 Are all consecutive
Step-by-step explanation:
-1 + -2 + -3 = -6
The answer is 3% I’m sure it is I’m very smart
