A service station will be built on the highway, and a road will connect it with cray. How long will the new road be?

maxonik [38]

Answer:

46.2 mi is the right answer.

Step-by-step explanation:

In this question we will follow the property of congruence of two triangles.

Here two triangles formed are triangle formed by Alba, Cray and Blare and a triangle formed by Service station, Cray and Blare.

The distance between Alba and Blare = 130 mi

The distance between Alba and Cray = 120 mi

As we know in the congruent triangles all sides are in the same ratio.

Now we apply the property of the theorem

$\frac{Distance(Alba-Cray)}{Distance(Alba-Blare)}= \frac{Distance(Cray-Service station)}{Distance(Cray-Blare)}$

$\frac{120}{130}=\frac{x}{50}$

$x=50\frac{120}{130}$

x = 46.2 mi

10. Find the area of the shaded region.

Semenov [28]

Answer:

Area = 114

Step-by-step explanation:

We first must find the area of the larger outside rectangle.

Area = length × width

15 × 8 = 120

Then we find the area of the smaller inside rectangle.

4 × 1.5 = 6

Since the small rectangle is not shaded we have to subtract its area from the larger shaded rectangle's area.

120 - 6 = 114
