Answer:
Step-by-step explanation:
Use the right triangle formula c^2=a^2+b^2
C is the number of the hypothenuse while b and c are the 2 others.
16^2=7^2+a^2
256=49+a^2
now solve for the equation.
a^2=207
now take the square root of both.
a=![\sqrt[2]{207}](https://tex.z-dn.net/?f=%5Csqrt%5B2%5D%7B207%7D)
Answer:
First one
Step-by-step explanation:
3/4 with the main number divide it
B) No, because opposite sides are not parallel
Step-by-step explanation:
Given this information, assume that quadrilateral WXYZ is a parallelogram then we expect;
Parallel sides to be : WX // YZ and XY // WZ
Additionally, we know parallel sides have equal gradient thus;
The slope of side WX= slope of side YZ and the slope of side XY= that of side WZ
However, from the information given, m of WX= 1/3 and that of YZ is -3, thus the two sides are not parallel to each other but perpendicular to each other because the product of their slope equals -1.
