Answer:

For example: 0=1 This is false because we know zero can't equal one. Therefore we can conclude that the problem has no solution. You can solve this as you would any other equation. 13x−5(x−4)=8x+513x−5x+20=8x+58x+20=8x+58x−8x+20=8x−8x+520=5 We see this is a false statement because 20 does not equal 5.

Step-by-step explanation:

number 2 the answer is b

Answer:

C = 28.9

Step-by-step explanation:

Given the right angled triangle, ∆BCD, you are required to find the measure of angle C.

Apply the trigonometric ratio formula to find m < C.

Adjacent side = 7

Hypotenuse = 8

Trigonometric ratio formula to apply would be:

cos(C) = \frac{7}{8}

cos(C) = 0.875

C = cos^{-1}(0.875)

C = 28.9

(To nearest tenth)
