Answer 1

Answer:

right angle triangle

Step-by-step explanation:

2x+3x-10+110-x

4x/4x =80/4x

x=20°

A=40°

B=50°

C=90°

Answer 2

Answer:

∠A=40°

∠B=60°

∠C=90°

The triangle is an right-angled triangle.

Step-by-step explanation:

We know that the measures of all Angle in any triangle is 180°

So,

According to the question

$2x + 3x - 10 + 110 - x = 180$

$= > 5x - 10 + 110 - x = 180$

$= > 4x - 10 = 180 - 110$

$= > 4x = 70 + 10$

$= > x = \frac{80}{4}$

$= > x = 20$

Now,

We know that x = 20°

Therefore,

∠A = 2x

$= > 2(20)$

$= > 40$

So ∠A = 40°

Now,

∠B = 3x-10

$= > 3(20) - 10$

$= > 60 - 10$

$= > 50$

So ∠B = 50°

Now,

∠C = 110-x

$= > 110 - 20$

$= > 90$

So ∠C= 90°

As one of the angle is 90° so it is a right-angled triangle

( according to classification of angles because that is only ask d in the Question)

Hope it helps you!!
