Answer:
step 1. <2 + 40° = <1
step 2. <1 + 72° = 180°
step 3. <1 = 108°
step 4. <2 = 108° - 40° = 68°.
So u just do 27*0.45 to get 12.15 and subtract that to get 14.85
Let us Verify Option - B
If Option - B is the Solution it should satisfy the Equation.
Given Equation : 7x - 5y = 28
Substituting x = 4 and y = 0 in the Equation, We get :
⇒ 7(4) - 5(0) = 28
⇒ 28 = 28
⇒ Ordered pair (4 , 0) is the Solution of the Equation 7x - 5y = 28
⇒ Option B is the Answer
