Let the triangle be ΔABC

The sum of angles in triangle is 180∘

 45∘+60∘+∠C=180∘∠C=180−45−60∠C=75∘

Explanation

Given the base of a right angled triangle is 8 m and its hypotenuse is 10 m

Then height =(10)2−(8)2​=100−64​=36​=6 cm

Then area of triangle =21​×8×6=24 sq cm

Explanation

35 men completed the remaining job in 12 days.
Now the same job has to be done by 30 men.
We know that, M1​D1​=M2​D2​
Required time =3035×12​=14 days
Delayed time =(14−13)=1 day

Explanation

Let total money be X

According to the question, we have the equation:

x/6 + x/8 + x/2 + 55 = x

Multiply through by 24 to eliminate the fractions, we get:

4x + 3x + 12x + 1320 = 24x

19x + 1230 = 24x

Subtracting 19x from both sides. 

we have:

1320 = 5x

Dividing both sides by 5, we get:

x = 264
