Help pls dont give just the answer pls step by step so i can understand
1 answer:
Answer:
y=14
Step-by-step explanation:
Since this is an isosceles triangle due to opposite sides being congruent, the base angles would also be congruent.
plug in 25 in 2x and you would get 50°
Since the sum of a triangle is 180° you could set up an equation
Then, add 50+50=100+10=110
then you would then have
subtract 110 from 180, leaving you with 70
then divide and you would get 14
Check:
5(14)+10+50+50= 180

via the angle sum formula of sin
which proves the second choice
the third choice is wrong since for x=0,y=0 it will show that 2=1 which is incorrect
for the fourth one you can do some thing similar to choice one just expand the sum formula of sin and that should be true too
so
the first , the second and the fourth are all true
Answer:
Step-by-step explanation:

Required
Which is correct
Calculate g(6) and f(6)
<em>(a) is false, because g(6) > f(6) i.e. 24 > 9</em>
<em></em>
Calculate f(7) and g(10)
<em>(b) is false, because f(7) < g(10) i.e. 11 <36</em>
<em></em>
Calculate f(5) and g(3)
<em>(c) is true, because f(5) < g(3) i.e. 7 <15</em>
