Answer:
17.5
Step-by-step explanation:
The perimeter is the sum of the side lengths:
perimeter = XZ +WZ +WX
The figure shows us WX = WZ, so we can rewrite the formula as ...
perimeter = XZ +2·WZ
Filling in the given values, this becomes ...
50 = 15 + 2·WZ
35 = 2·WZ
35/2 = WZ = 17.5
The length of WZ is 17.5 units.
Answer: it will be 3 feet high
Step-by-step explanation: what you do is read what it is asking you again and the answer is 3
See image for naming of the sides: the medians are
ab, bc, and ac; and sides are a, b, and c
Pick one median, say, ab. The following are true:
ab < a
ab < b
->
ab + ab < a + b
ab < 0.5*(a+b) | add 0.5*c to the right hand side (does not change inequality)
ab < 0.5(a+b+c) = half perimeter
so ab < half perimeter
Same argument for bc, and ac holds.
Answer:
w=120°
x=45°
y=30°
Step-by-step explanation:
AT=PR, AR=PT
Therefore, y=30°
y+45°=x+30°
x=45°
In triangle:
y+30°+w=180°
w=120°
Hope it helps! :)
