Answer:
25+40
Step-by-step explanation:
for the area of a triangle you multiple the base times the height. for the area of the square it is the length times width.
NOTE: to completely answer just add 25+40
15
Explanation:
you just divide 90 by 6
Answer:
x = 114
Step-by-step explanation:
Since p and q are parallel, the angle = 104° is equal to the angle = ( x - 10 )° by alternate exterior angles.
That means 104 = ( x - 10 )
+10 +10
= 114 = x
We are given a system of equations,

This will translate into a 2x2 matrix of coefficients (because 2 equations and 2 unknowns),

The matrix will then be applied to the vector (lower dimensions on top),

And the result vector will be whats on the other side of equals sign,

So to put everything together,

Hope this helps :)
