Isocoleese means 2 angles are same, normally the base angles

so since it says they measure 42
rememeber that all angles in traingle add to 180
so base angles+vertex angle=180
base angles aer both 42 so
2 times 42+vertex angle=180
42 times 2=84
so
if veretx angle=z then
84+z=180

answer is B

Find the limit<br> Picture below

pogonyaev

Answer:

a. 4

Step-by-step explanation:

We want to find;

$\lim_{h \to 0} \frac{f(2+h)-f(2)}{h}$

If $f(x)=x^2$ .

$f(2+h)=(2+h)^2$

$f(2+h)=4+4h+h^2$

Also;

$f(2)=2^2$

$f(2)=4$

This implies that;

$\lim_{h \to 0} \frac{4+4h+h^2-4}{h}$

Simplify;

$\lim_{h \to 0} \frac{4h+h^2}{h}$

Factor to get;

$\lim_{h \to 0} \frac{h(4+h)}{h}$

Cancel the common factors.

$\lim_{h \to 0} 4+h$

Substitute h=0 to get

$\lim_{h \to 0} 4+h=4+0=4$

Solve the system of equations.

Murrr4er [49]

I would use elimination
2x+3y = 7
2x-y = -5
Subtract those equations
4y = 12
Y = 3
Now plug in 3 for any y value
2x - 3 = -5
2x = -2
X = -1, y = 3
