You have to build an equation to find the answer,
angles in a straight line add upto 180°
so your equation would be,
12x+30°=180°
-30 -30
=12x=150°
÷12 ÷12
=x=12.5°
now find the measures of the angles by using 12.5 as x.
angle EAF= 2x
=2×12.5
=25° degrees
angle DAE= 4x
=4×12.5
=50°degrees
angle CAD=6x
=6×12.5
=75°degrees
check,
30+25+50+75=180°degrees
hope this helps.......
Thats How you go from slope to to standard form
Step-by-step explanation:
3 cookies= 240 cal
∴ 1 cookie= 240÷3 cal
∴ 5 cookies= (240÷3) × 5
⇒ 240÷3= 80
⇒ 80 × 5= 400
[ans] 400 cal
Hi!
So the original formula for a problem likes this or a quadratic is:
ax^2 + bx+ c
so a is the accelaration; b is the initial velocity; and c is the initial height
so none of those are the zeros, which means c is out
zeros are the x values when y is 0, that also means when the parabola crosses the x axis
so d is out too because the maximum height is the vertex which mean that there would probably be a y value. in some cases the vertex is the zero, but not here
B is out because x isn't time it is distance
your answer is A!
Hope this helps!
Grouping is when you have to terms that are the same inside the parenthesis and a different or same number outside the parenthesis and then the one inside the parenthesis u are going to group them not combined them and write them once and the numbers inside the parenthesis group them together by adding them and put parenthesis between them
Ex
5(4x+1)10(4x+1)
(5+10)(4x+1)
