??????????what????????????
Alright, so you know that the formula for the area of a triangle is a=bh/2
First start out by identifying your base and height.
Base is the side that the shape is "standing on", in this case, that would be 9cm.
Now, the height is the measurement that is perpendicular (90 degrees to the base), which in this case is 12 cm.
Now, plug these values into your formula
(12)(9) /2 = 54 cm squared! hope this helps :)
-19x+9 is the answer
First distribute -5 and -7 once you that you’ll get -5x+30 and -14x-21 so now you have -5x+30-14x-21 you then are gonna combine like terms so -5x-14x is -19x and 30-21 is 9 and so you’ve simplified all you can and end up with -19x+9
Answer:
18.8 feet
Step-by-step explanation:
\tan M = \frac{\text{opposite}}{\text{adjacent}}=\frac{x}{5.4}
tanM=
adjacent
opposite
=
5.4
x
\tan 74=\frac{x}{5.4}
tan74=
5.4
x
5.4\tan 74=x
5.4tan74=x
Cross multiply.
x=18.832\approx \mathbf{18.8}\text{ feet}
x=18.832≈18.8 feet
Type into calculator and roundto the nearest tenth of a foot.

Answer: 20k
Step-by-step explanation: product means to multiply. Use k for the unknown number. 20 times k can be written as 20k.
