Answer:
Step-by-step explanation:
v = 40° ( being vertically opposite angles )
Answer:
let's find the gradient first. (m)
Step-by-step explanation:
(10,3) (6,31)
y²-y¹/x²-x¹
31-3/6-3
28/3
(m) =28/3
y-y¹=m(x-x¹)
let's take y¹=3, x¹=10 and m= 28/3
y-3=28/3(x -10)
y-3=(28/3)x -128/3
taking LCM=3
3y-9=28x-128
3y=28x -128+9
3y=28x-119
Soo your equation is:
3y=28x-119
Answer:
8 years.
Step-by-step explanation:
Mara is 6.
6+8=14
Alberto is 20.
20+8=28
14*2=28.
In 8 years, Alberto will be twice Mara's age.
Answer:
A) The ratios are both identical (3/5 and 3/5)
Step-by-step explanation:
x:-
3 = opposite
5= hypotenuse
Sin x= 3/5
------
Y;-
3= adjacent
5= hypotenuse
Cos y= 3/5

Answer:
h=14
Step-by-step explanation:
So since the triangular shape is a right triangle, we can use a Pythagorean triple. For this question, lets use (5,12,13). But, if you just want to use the formula:
5^2+x^2=13^2
25=x^2=169
x^2=144
x=12
That means a part of h is 12. BUT, we also have an extra two ft on top of the triangle, so h=12+2=14.
