Angle 0 lies in the second quadrant and sin 0 = 3/5 cos= coy =

Elza [17]

Consider the right triangle ABC with legs AB=4, AC=3 and hypotenuse BC=5. Angle B has
$\sin B=\frac{opposite}{hypotenuse} = \frac{3}{5}$ and
$\cos B = \frac{adjacent}{hypotenuse} = \frac{4}{5}$ .

Since O lies in second quadrant $\cos O\ \textless \ 0$ and
$\cos O= -\cos B =- \frac{4}{5}$ .
Answer: $\cos O=- \frac{4}{5}$ .

Jacob is 5 5/6 feet tall. Linda is 5 1/4 feet tall. How much taller is Jacob?

SCORPION-xisa [38]

This problem boils down to 5/6 - 1/4

To subtract these fractions you need a common denominator.

I'll use 12

The first fraction becomes 10/12 and the second fraction becomes 3/12

10/12-3/12 = 7/12

So Jacob is 7/12 of a foot taller than Linda.

Also note than since 12 inches = 1 foot, you could say Jacob is 7 inches taller than Linda

DerKrebs [107]

Answer:

So first converthem into a deciaml if the number line is ordered by decimals or make them from least to greatest, left to right.

Decimal:

If asking for s decimal, the -1 is definitely the least so -1. For -5/7, it’s just -0.71 (rounded), for 2/7, its 0.28 and for 6/7 its 0.86.
