The answer is x= -4 and x= 0, simply subtract 16 on both sides and solve it with x-2 = -2 and x+2= -2
Answer:
85°
Step-by-step explanation:
Sum of angles in a Quadrilateral = 360°
Angles include : 65°, 123°, 87° and x°
65 + 123 + 87 + x = 360
x + 275 = 360
x = 360 - 275
x = 85°
Answer:
<u>BC = 3.1666</u>
Step-by-step explanation:
To solve this you need to know that cosine∅ = adjacent/hypotenuse. We already know that hypotenuse = 5 and that ∅ = 70*. By substituting these in you will get cosine 70* = adjacent/5. Evaluate cosine 70* on the calculator and get 0.633... Multiply both sides by 5 and get adjacent is about equal to 3.1666. Because BC is the adjacent side of the triangle, this is the length of BC.
