Based on your value of x in question #1, what is the value for ∠EHF

Ludmilka [50]

Answer:

∠EHF = 132°

Step-by-step explanation:

Both angles lie on a straight line.

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

∠EHF + ∠FHG = 180°

2(x) + 48° = 180°

2(x) = 180° - 48°

2(x) = 132°

x = 66°

Then ∠EHF :

2(x)

2(66)

132°

Isosceles triangle ABC has a perimeter of 96 centimeters. The base of the triangle is Line segment A C and measures 24 centimete

Mnenie [13.5K]

<h2>Answer:36 $cm$ </h2>

Step-by-step explanation:

Given that $ABC$ is isosceles triangle.

A isosceles has two sides equal an the third side is the base.

So, $AB=BC$ ...(i)

Given that length of the base $AC=24$

Given that the perimeter of the triangle is $96$

So, $AB+BC+AC=96$ ...(ii)

Using (i) and (ii),

$AB+AB+AC=96\\2AB+24=96\\2AB=72\\AB=36cm$
