Question

A triangle has two angles measuring 60° and 70°. What type of triangle is this?

a) Right Angled Triangle

b) Obtuse Angled Triangle

c) Acute Angled Triangle

d) Equiangular Triangle

Answer 1

Answer:

acute angleed triangle

Step-by-step explanation:

let the third angle be x

then,

x + 60 + 70 = 180

x + 130 = 180

x = 50

therefore , the triangle is acute angled triangle

Answer 2

Step-by-step explanation:

1st angle=60°

2nd angle =70°

let 3rd angle=x

Then according to angle sum property of triangle

$\longrightarrow \bf{60 + 70 + x = 180} \\ \longrightarrow \bf{x = 180 - 130} \\\longrightarrow \bf x = 50$

Here you can see that all the angle of the triangle is less than 90° so it is acute angled triangle

$\huge\bf \mathbb{MORE \: TO \: LEARN}$

Acute angle =a angle less than 90°

Obtuse angle = a angle more than 90°

Right angle=a angle at 90°

Equiangular angle=name only suggest that all the angles should be equal

Angle sum property of triangle states that sum of angle of any triangle should be equal to 180
