The first triangle’s area is 48.75. But since you round it to the nearest tenth, it’s 48.7.

Use the formula a=1/2bh to find the area of a triangle.
A= 1/2• 13 • 7.5
A= 6.5• 7.5
A= 48.75 —-> 48.7 square inches.

Sorry, I can only do one because of homework, but make sure to use that formula! Hope this helped.

kipiarov [429]

x=96


all interior angles equal 180


Subtract exterior andgles by 180 to get interior angles because they are supplementary

180-134=46

180-130=50


Get the third angle inside the triangle

180-50-46=84


subtract by 180 to get x because they are supplementary

180-84=96


Therefore x =96
