"d + (-d) = 0" is the one equation among the following choices given in the question that <span>illustrates the additive inverse property. The correct option among all the options that are given in the question is the fourth option or option "D". I hope that this is the answer that has actually come to your desired help.</span>
Given: Area of triangle =84 square feet
height= 4 feet greater than 4 times its base
h=4b +4
Area of triangle= 1/2 ( b) (h)
plugging for area and height
84=1/2 ( b)* (4b+4)
168=4b² +4b
4b²+4b-168=0
taking out 4 common as gcf
b²+b-42=0
factorising we get
(b+7)(b-6)=0
b=6, -7
since length cannot be negative so base =6feet
height= 4b+4 = 24+4=28 feet
Answer: 61°
because this is a parallelogram
=> m∠X = m∠Z
⇔ 7x + 5 = 8x - 3
⇔ x = 8
with x = 8 => m∠X = 7.8 + 5 = 61°
