That be 23-5= 18 then -6
-- - = 0.2 so that means X=0.2
23
Step-by-step explanation:
All you need is substarcting the angles
cbf=180-72
cbf=108°
dbe=180-90-72
dbe=18°
abd=90° -right angle.
abc=180-18-90
abc=72
Answer:
16.33 feet
Step-by-step explanation:
17.5 / 11.25 = x / 10.5
x = 17.5 * 10.5 / 11.25 = 16.33
Answer:
<h2>D = 28°</h2>
Step-by-step explanation:
To find angle D we use tan
tan ∅ = opposite / adjacent
From the question
DE is the adjacent
EF is the opposite
DE = 13
EF = 7
tan D = 7/13
D = tan-¹ 7/13
D = 28.3°
D = 28° to the nearest tenth
Hope this helps you
