Answer: 175 robberies

Step-by-step explanation:

Robberies last year= 243

Robberies has reduced by 28% which means there are (100-28)% = 72% robberies this year.

Number of robberies this year= 72% of 243 = 72/100 × 243 = 174.96 = 175.

There are 175 robberies this year

Answer: 175

Step-by-step explanation:

The original number of robberies = 243

It has been reduced by 28% , to find the present number of robberies , all we need do is to find 72% of 243. That is

72% x 243

= 0.72 x 243

= 174.96

Therefore , the number of robberies this year to the nearest whole number will be 175

If WXY is equilateral and WZY is<br> isosceles, find each missing measure.
timurjin [86]

Answer:

m∠1 = 60°

m∠2 = m∠4 = 39°

m∠3 = m∠5 = 21°

Step-by-step explanation:

ΔWXY is a equilateral angle,

Therefore, all angles of the the triangle are equal in measure.

m∠W + m∠X + m∠Y = 180°

3m∠W = 180°

m∠W = 60°

Since, ΔWZY is an isosceles triangle,

m∠3 = m∠5

m∠3 + m∠Z + m∠5 = 180°

m∠3 + 138° + m∠3 = 180°

2m∠3 = 180 - 138

m∠3 = 21°

Therefore, m∠3 = m∠5 = 21°

Since, m∠2 + m∠3 = 60°

m∠2 = 60 - 21

        = 39°

Since, m∠4 + m∠5 = 60°

m∠4 = 60 - 21

        = 39°

m∠1 = 60°
