Given:<br> RS = 3x - 16<br> ST = 4x - 8<br> RT = 60<br> Solve for RS.
Aleks04 [339]

The value of RS in the line segment is 20

To solve for RS :

From the line segment attached :

The information given is :

RS = 3x - 16

ST = 4x - 8

RT = 60

RT = RS + ST

60 = 3x - 16 + 4x - 8

60 = 7x - 24

60 + 24 = 7x

84 = 7x

Divide both sides by 7

84/7 = x

x = 12

RS = 3x - 16

RS = 3(12) - 16

RS = 36 - 16

RS = 20

HENCE, RS = 20

Triangle RST has sides measuring 22 inches and 13 inches and a perimeter of 50 inches. What is the area of triangle RST? Round t
VladimirAG [237]

Using the Heron's formula, the area of the triangle is: D. 95 square inches.

<h3>What is the Heron's Formula?</h3>

Area = √[s(s - a)(s - b)(s - c)] where s is half the perimeter, or (a + b + c)/2.

Given the following:

s = semi-perimeter = 1/2(50) = 25 in.

a = length of side a = 22 in.

b = length of side b = 13 in.

c = length of side c = 50 - 22 - 13 = 15 in.

Plug in the values

Area = √[25(25 - 22)(25 - 13)(25 - 15)]

Area = √[25(3)(12)(10)]

Area ≈ 95 square inches.

The sum of Janos' age and David's age is 34 years. Five years ago the sum of twice Janos' age and three times David's age was 61
marishachu [46]
Because if you divide 34 by 2 you get 17. Then subtract 17 minus 5 which equals 12 so you multiply 12 times 2 for Janos' age and 12 times 3 for David's age which makes 60 but not 61. Their present age is 17.
