Answer:

6

Step-by-step explanation:

since it's a right triangle you can use the Pythagorean Theorem

2.7² + b² = 6.5²

7.29 + b² = 42.25

b² = 34.96

b = \sqrt{34.96} which equals 6 when rounded to the nearest tenth

Suppose you buy a $50 coffee maker in an area where the sales tax is 8%. When you check out, 8% of $50 would be added to your to
ASHA 777 [7]

Answer:

4

Step-by-step explanation:

8% is also 8/100. This would be true for all percents 0 to 100%. If it were 42% it can be written as 42/100.

So, 8% is 8/100. If you want to find 8/100 of 50 multiply them.

8/100 * 50/1 = (8*50) /100

400/100 = 4

SOMEONE EASE ANSWER NUMBER 4?
nlexa [21]

On analyzing the question we can say that the angle ∠JKM of the triangle ΔJKL would be 42 as line MK bisects ∠JKL into ∠JKM & ∠MKL.

From the question it follows that line MK bisects angle ∠JKL into ∠JKM & ∠MKL where M is the point in the interior of ∠JKL.

Therefore, as we have given  m∠JKL = 84 & m∠MKL  = 42

and we have to find m∠JKM , we will simply write the equation as follow

m∠JKL = m∠JKM + m∠MKL

Inserting values we get,

84 = m∠JKM + 42

m∠JKM = 42

Hence, angle m∠JKM  of the triangle ΔJKL is  42.
