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:
Yes
Step-by-step explanation:
Multiplicative Inverse of rational number:
When we multiply a rational number and its multiplicative inverse, we get 1
Now,multiply this with (3/-17)
So, -5 2/3 is the multiplicatice inverse of 3/-17
Nine million nine thousand and nine
