Answer:

84 degrees

Step-by-step explanation:

132+54 = 186 degrees

186+90 = 276 degrees

as this is around a point it totals to 360 degrees

360 degrees - 276 degrees = 84 degrees

hope this helps

Answer:

x = 84

Step-by-step explanation:

Sum of angles around a point = 360

i.e,

=> 54 + 132 + 90 + x = 360

=> 276 + x = 360  

=> x = 360 - 276    

=> x = 84

One number is 4 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 538,
larisa [96]

Answer:

73

292

173

Step-by-step explanation:

x = first number

4x = second number

100 + x = third number

x + 4x + 100 + x = 538

6x + 100 = 538

6x + 100 - 100 = 538 - 100

6x = 438

6x/6 = 438/6

x = 73

Check:

73 + 4(73) + 100 + 73 = 538

73 + 292 + 173 = 538

538 = 538

99. What is the greatest prime factor of 5,355?<br> A. 17<br> B. 51<br> C. 119<br> D. 131<br> E. 153
NemiM [27]
Hello,

5355 is divisble by 3 since 5+3+5+5=18 is divisible by 3
5355=3*1785
1785 is divisble by 3 since 1+7+8+5=21 is divisible by 3
1785=3*595
595 is not divisible by 3 but by 5
595=5*119
119 is divisible by 7 since 1*2+1*3+9*1=14 is divisible by 7.
119=7*17

17 is prime
