Answer:
ANSWER: ADC=82
bda = 144
(7x+34)+(9x+46)=144
16x+80=144
16x=64
x=4
9(4)+46=82
adc=82
Step-by-step explanation:
The box method or latitude or longitude.
For every value tht x increases, y decreases by 3
-3x
Then to find the y intercept, look at 0's corresponding value (8)
-3x+8
The area of a traingle is
So we need to know the base and the height
To work out the sides of a right angle triangle we can use a²+b²=c
c is the hypotenuse and a and b are the other sides
Because this triangle is isoceles we know that a and b are the same
a²+b²=c²
a²+a²=c²
2a²=c²
2a²=(x√6)²
2a²=(x√6)(x√6)
2a²=x²+x√6+x√6+6
2a²=x²+x√6+x√6+6
a²=
