Find the area and perimeter of the triangle in the picture. (the missing unit is 8.5 if you need that to solve)

1 answer:

6 0

The area is when you muliply base×hight wich is 17×8.5=144.5 then divide by 2 so 144.5÷2=72.25

perimeter is when u add all sixes so its 17+8.5+19=44.5
P=44.5

Answer:

See Explanation;

Step-by-step explanation:

The given vectors are;

$v_1=\:\:$ and $v_2=\:\:$

a) To add or subtract two vectors, we add or subtract their corresponding components

$v_1+v_2=\:\:+\:\:$

$v_1+v_2=\:\:$

$v_1-v_2=\:\:-\:\:$

$v_1-v_2=\:\:$

$v_2-v_1=\:\:-\:\:$

$v_2-v_1=\:\:$

-32>-5+9z Solve for x.

Darya [45]

Answer:

I do not know how it wants the answer, but it is -4.1 repeating.

I am guessing you meant solve for z too? If there are multiple choice I can help choose the right one.

Step-by-step explanation:

-32>5+9z

subtract 5 from both sides

-37>+9z

then divide 9 from both sides

-4.1111 repeating > z
