Answer:

The answer of your question is: x = 5

Step-by-step explanation:

It's and isosceles triangle then ∠ A = ∠C

73 = 8y - 7

8y = 73 + 7

8y = 80

y = 80 / 8

y = 10

∠ C = 8(10) -7

∠ C = 73°

The sum of the internal angles in a triangle equals 180°

∠A + ∠B + ∠C = 180°

73° + (6x + 4) + 73° = 180° Substitution

6x + 4 = 180 - 73 - 73

6x =34 - 4

6x = 30

x = 30 / 6

x = 5

Can a 180 degrees angle be a obtuse triangle?

Aleksandr [31]

Answer:

Yes and no, I'll explain below

Step-by-step explanation:

An obtuse triangle can have either a 90 degree angle or an 180 degree angle. This reason being said, an obtuse triangle has ONLY one angle that is greater than 90 degrees. But the sum of any given triangle is 180. Hope this helps!

Tomb trees are standing side-by-side in the sunlight one is 50 feet tall and the other is 20 feet tall if the taller tree cast a

8090 [49]

Answer: Length of shorter tree = 7.2 feet .

Step-by-step explanation:

Given : Height of two trees as 50 feet and 20 feet.

At same time the angle made by sun rays would be same for both trees.

Both trees are vertical to the ground making right angle so triangles made by both triangles must be similar.

Corresponding sides of similar triangles are proportional.

So $\dfrac{\text{length of the shadow of the shorter tree}}{\text{height of shorter tree}}=\dfrac{\text{length of the shadow of the bigger tree}}{\text{height of bigger tree}}\\\\=\dfrac{\text{length of the shadow of the shorter tree}}{20}=\dfrac{18}{50}\\\\\Rightarrow\ \text{length of the shadow of the shorter tree}=\dfrac{18}{50}\times20\\\\\Rightarrow\ \text{length of the shadow of the shorter tree} = 7.2$
