Find the measurement of sides

Mathematics
1 answer:
mestny [16]3 years ago
7 0

Answer:

(a) a ≈ 22.7 meters, (b) c ≈ 10.6 meters, (c) ∠A = 65°

Step-by-step explanation:

assuming side a/c is side BC/AB since it's opposite of angle A/C

(a) SOH CAH<em>(cos = </em><em>adjacent side/hypotenuse</em><em>)</em> TOA

=> cos (25°) = BC/AC or a/b

=> cos (25°) = a/25

=> a = cos (25°) × 25

=> a ≈ 22.7

(b) SOH<em>(sin = </em><em>opposite side/hypotenuse</em><em>)</em> CAH TOA

=> sin (25°) = AB/AC or c/b

=> sin (25°) = c/25

=> c = sin (25°) × 25

=> c ≈ 10.6

(c) 180° - 25° - 90°(the right angle) = 65°

Given:

In an isosceles triangle,

One base angle = (4x-15)°

Vertex angle = 95°

To find:

The value of x.

Solution:

Let the triangle be ABC.

We have,

m\angle A=95^\circ

m\angle C=(4x-15)^\circ

Since ABC is an isosceles triangle and AB=AC, therefore, the base angles are equal.

m\angle B=m\angle C=(4x-15)^\circ

Using angle sum property of triangles, we get

m\angle A+m\angle B+\angle C=180^\circ

95^\circ+(4x-15)^\circ+(4x-15)^\circ=180^\circ

(8x+65)^\circ=180^\circ

(8x+65)=180

On further simplification, we get

8x=180-65

8x=115

x=\dfrac{115}{8}

x=14.375

Therefore, the value of x is 14.375.

There are total 4 outcomes

We can get:
Head, Head
Head, Tail
Tail, Head
Tail, Tail

So, tossing 2 coins, result in 4 possible outcomes which make the sample space.

So correct answer is option B
