Answer 1

Easy

Explanation:

as u can see this a obtuse angle witch mean that x= 190

Answer 2

x = 2.75

Explanation:

Given sides of triangle,

→ AB = 2.25 + x

→ AC = 3

→ BC = 4

Now we have to,

→ Find the required value of x.

Formula we use,

→ Pythagoras theorem

→ AB² = AC² + BC²

Forming the equation,

→ (2.25 + x)² = (3)² + (4)²

Then the value of x will be,

→ (2.25 + x)² = (3)² + (4)²

→ (2.25 + x)² = 9 + 16

→ (2.25 + x)² = 25

→ 2.25 + x = √(25)

→ 2.25 + x = 5

→ x = 5 - 2.25

→ [ x = 2.75 ]

Hence, the value of x is 2.75.
