Answer:
x = 120
y = 30
Step-by-step explanation:
Given that RST is equilateral, each of its interior angles will be 60 degrees
Looking at x, it lies on a starting line with one of the interior angles of RST
The sum of angles on a straight line is 180
Thus;
x + 60 = 180
x = 180-60
x= 120
Looking at triangle RSU, the markings indicates that we have an isosceles triangle
For an isosceles triangle, the base angles are equal in value
This means that SRU is also y
Mathematically, the sum of angles in a triangle is 180
Hence;
x + y + y = 180
x + 2y = 180
120 + 2y= 180
2y = 180-120
2y = 60
y = 60/2
y = 30
Answer: 13 and 9
Step-by-step explanation:
because since there are two people 38-(8x2)=22
The only numbers that add up to 22 that have a difference of 4 are 13 and 9
Another way:
T=C+4
T+8+C+8=38
C+4+C+8=
Answer:
$60745
Step-by-step explanation:
2,5÷100×2200
=55
55+2200
=2255
therefore 63000-2255
= $60 745
Answer:
one card takes 1/12 of an hour or 60/12=5 minutes.
she has 3/4 of an hour or 60×3/4=45 minutes
number of cards she can make =45/5=9
The correct answer is a.y=3x-4
