Answer:
length 21yd
width 15yd
Step-by-step explanation:
Actually it does factor
x(x+6)=315
x²+6x=315
x² +6x - 315 = 0
(x+21)(x-15) = 0
x= -21. discard as can’t have a negative distance
x=15
So dimensions are 15 and 21
Answer:
4) Alternate Interior angles 5) Parallel lines property.
Step-by-step explanation:
The question is asking us to Complete the statements to prove that line AB ⩭ to line CD and line BC ⩭ to line AD.
In statement 4 .∠CAB is congruent to ∠ACD as AB is parallel to CD and ∠BCA is congruent to∠CAD as AD is parallel to BC and these are Alternate interior angles to the parallel lines .
In statement 5.m∠CAB =∠ACD and ∠BCA = ∠CAD as by property of parallel lines Alternate interior angles are equal.

Answer:
Approximately 360.3
Step-by-step explanation:
△ABC, AB = BC and CH is an altitude.
Note in isosceles triangle the two base angle are equal.
And two sides are equal.
CH = 84 cm and m∠HBC = m∠BAC +m∠BCH
So yhe base angle = 50°
The length of tthe hypotenuse , lets cal it x
Sin 50 = 84/x
X = 84/sin 50
109.65 = x
For the The base
109.65²-84²=b²/4
141 = b
Perimeter = 2*109.65 + 141
Perimeter = 360.3
Approximately 360
