The perimeter is 36 so, (x+3)+(2x-9)+x = 36 solve and you will get x=12, then substitute x into the triangle you will have 9,12 and 15. Find the area by using 1/2 x base x height and the area is 54 inches^2 . The answer is (b)

Step-by-step explanation:

a/q

x + x - 3 + 2x - 9 = 36

4x - 12 = 36

4x = 36 + 12 = 48

x = 48/4 = 12

x = 12

so,

x = 12

x - 3 = 12 - 3 = 9

2x - 9 = 2(12) - 9 = 15

we know,

area = 1/2 × base × height

so,

→ 1/2 × 12 × 9

→ 1 × 6 × 9

→ 54 inches.

Leviafan [203]
First turn them into improper fractions to make things easier: 31/8 and 155/4.
You would then do 155/4 divided by 31/8, and with the same-change-flip, do 155/4 times 8/31, which is 10

Veronika [31]

Answer:

(a) 39,208

(b) 65%

Step-by-step explanation:

(a) The car loses 10% the first year and 15% the second year so that’s 35% lost in total after two years.

35% of 60,320 is 21,112

60,320 - 21,112 = 39,208

39,208 ÷ 60,320 = 0.65 (65%)

Craig made a mobile using geometric shapes including triangles shaped as shown. For what value of X and Y can you use a triangle
PolarNik [594]

Answer:

x = 3

y = 8

Step-by-step explanation:

In the given triangle FGH,

m∠F + m∠G + m∠H = 180° [Triangle sum theorem]

60° + 90° + m∠H = 180°

m∠H = 30°

If the given triangles FGH and TUV are congruent, their corresponding sides will be equal in measure.

m∠F = m∠T

7y + 4 = 60°

7y = 56

y = 8

GH ≅ UV

8x - 12 = 12

8x = 24

x = 3
