The diagram shows a triangle.

Free_Kalibri [48]

Answer:

c=3

Step-by-step explanation:

Angle sum of a triangle is 180°

(19c+16)°+13c°+(17c+17)°=180°

collect the like terms i.e

19c+13c+17c+16+17=180°

49c°+33°=180°

49c°=180°-33°

49c°=147

dividing by 49 both sides

49c/49=147/49

c=3

If Kaylee was 18 and Lylah was 45 how many years younger would Kaylee be??

SVETLANKA909090 [29]

You are trying to find how much younger Kaylee is than Lylah.

You would subtract her age from Lylah's.

45-18= 27

Kaylee was 27 years younger than Lylah.

I hope this helps!

Logan is a land surveyor. He wants to determine d, the distance across a lake that cannot be directly measured. He draws this di

Mice21 [21]

Answer:

The first option (5.7km)

Step-by-step explanation:

Since we have a right angle triangle and we know two of its sides we can easily find out the thirds side (the value of d) by using the Pathagoras Theorem. In our case 7 and d are our legs and the hypotenuse is equal to 9, so...

(Based on the Pathagoras Theorem)

$c^{2} = a^{2} + b^{2}$

$9^{2} = 7^{2} + d^{2}$

$d^{2} = 9^{2} - 7^{2} \\d^{2} = 81 - 49\\d^{2} = 32\\d = \sqrt{32}\\$

d ≈ 5.7km

There for aproximate distance across the lake is equal to 5.7km
