Answer:
x=27.5
FG=72.5
GH=60
HF=47.5
Step-by-step explanation:
Sum of angles in a triangle=180
Therefore, FG+GH+HF=180
Substituting the values we have,
(3x - 10) + (2x+5) +(x+20) = 180
Collecting like terms
3x+2x+x = 180 +10 - 5 - 20
6x = 165
X= 27.5
FG = (3x - 10) = 3(27.5) - 10
FG= 72.5
GH= (2x+5) = 2(27.5)+5
GH=60
HF= x+20 =27.5+20
HF=47.5
Answer: 40°
<u>Step-by-step explanation:</u>
There are 4 pink angles (labeled as "a") and each are the same measure.
There are 4 green angles (labeled as "b") and each measure 50°.
A circle is 360°
4a + 4b = 360
4a + 4(50) = 360
4a + 200 = 360
4a = 160
a = 40

I think you can round that but I think that's the answer.
Domain – All of the values that go into a relation or a function are called the domain. Range – All of the entities (output) which emerge from a relation or a function are called the range. All input values that are used (independent values) forms the Domain set.
