If PQR is a triangle,given that /PQ\=15m, /QR\=17m and /RP\=18m.Find the area of the triangle to the nearest whole number.

nydimaria [60]

Answer:

118.3 m²

Step-by-step explanation:

Step 1. Calculate the <em>semiperimeter</em> (s).

s = (p + q + r)/2

s = (17 + 18+ 15)/2

s = 50/2

s = 25 m

===============

Step 2. Calculate the <em>area</em> (A).

Use <em>Heron’s formula</em>:

$A = \sqrt{s(s-p)(s-q)(s-r)}$

$A = \sqrt{25(25-17)(25-18)(25-15)}$

$A = \sqrt{25\times8\times7\times10}$

$A = \sqrt{14 000}$

$A = 20\sqrt{35}$

A = 118.3 m²

Answer:

y = 45 and y = -45

Step-by-step explanation:

|y|/-3 = -15

Multiply each side by -3

|y|/-3 * -3= -15*-3

|y| = 45

The absolute value has 2 solutions, one positive and one negative

y = 45 y = -45

=$525

Step two:

Hence the five band members will share $525

each of them will receive

=525/5

=$105

The longer leg of a 30-60-90° triangle is 18. What is the length of the other leg?

Karolina [17]

Answer:

Step-by-step explanation:

In a 30-60-90 triangle, the longer leg is $\sqrt{3}$ times larger than the smaller leg. The length of the shorter leg is therefore:

$\dfrac{18}{\sqrt{3}}= \\\\\\\dfrac{18\sqrt{3}}{3}= \\\\\\6\sqrt{3}$

Hope this helps!
