Answer:
value of y = 95°
Step-by-step explanation:
=》128° + 72° + 65° + y = 360°
( because sum of all angles
of a triangle = 360° )
=》265° + y = 360°
=》y = 360° - 265°
=》y = 95°
i hope you got it.
Answer:
76.9690 square units (rounded off to four decimal values)
Step-by-step explanation:
The diameter of the semicircle is 14 units
The radius of the semicircle is thus 14 ÷ 2 = 7 units
Area of a semicircle is given by: 
× π × r²
In our case, the area is = × π × 7² = 76.9690200129 square units
Or 76.9690 square units (rounded off to four decimal values)
The problem needed to say that when he did the shading,
he only shaded WHOLE PARTS.
For the rectangle that he shaded 1/3 of, how many parts could it have ?
It could have 3, 6, 9, 12, 15, 18, 21, etc. parts ... the multiples of 3.
For the rectangle that he shaded 1/4 of, how many parts could it have ?
It could have 4, 8, 12, 16, 20, etc. parts ... the multiples of 4.
Both rectangles have the same number of parts.
What's the smallest number on both of those lists ?
It's called the "least common multiple of 3 and 4".
It's the smallest number that they both go into.
It's 12 .
X-8=3x+6
(Minus 3x and add 8 to group your variables)
-3x+x=8+6
-2x=14
-2x/-2 = 14/-2
X=-7
