Answer:
F(-2)=G(-2)
Step-by-step explanation:
Answer:
First, let one angle be a variable (eg: x) so that you can form expressions and solve.
Let the first angle be x°.
Then we can form expressions for the second and third angles using the information given.
First angle = x°
Second angle = (x + 10)°
Third angle = (3x)°
Since sum of angles in a triangle is 180°, we can form an equation.
x + (x + 10) + 3x = 180
Simplify and solve for x.
5x + 10 = 180
5x = 170
x = 34
Substitute x into the expressions to find the angles.
First angle = 34°
Second angle = 34 + 10
= 44°
Third angle = 3(34)
= 102°
Kate is 3 years old
Explanation:
Kate is x for example, then her father would be
x+32
In five years he would be x+32+5, x+37, but he would also be 5 times older.
Kate will also be x+5.
SO, we know that
x+37=5 · (x+5)
When we simplify, we get
x+37 = 5x+25
Simplify further, you get
12=4x, so
3=x
