Answer:

Answer:

AB = 17.3 cm

Step-by-step explanation:

We require to find the measure of ∠A then use the cosine ratio to calculate AB

sum the parts of the ratio 3 + 2 = 5 parts, then

90° ÷ 5 = 18° ← value of 1 part of ratio

∠A = 2 × 18° = 36°, thus

cos36° = (adjacent)/(hypotenuse) = (14)/(AB)

Multiply both sides by AB

AB × cos36° = 14 ( divide both sides by cos36° )

AB = (14)/(cos36) ≈ 17.3 cm

Which is the best estimate for the sum of 3/8 and 1/12¿

Answers

Estimating is an educated guess, so 3/8 is just less than half, and 1/12 is just a bit more than 0.  So you could estimate that 3/8 + 1/12 = roughly 1/2

 if you add 3/8 and 1/12 you get 11/24

7) 2(2x + 4) – 3(x - 1) = 11

Answers

Answer:

2(2x + 4) – 3(x - 1) = 11

4x+8-3x+3=11

4x-3x+8+3=11

x+11=11

x=0

Step-by-step explanation:

Answer:

x = 0

Step-by-step explanation:

Given

2(2x + 4) - 3(x - 1) = 11 ← distribute parenthesis and simplify left side

4x + 8 - 3x + 3 = 11

x + 11 = 11 ( subtract 11 from both sides )

x = 0
