Answer:
<I= 15degrees
Step-by-step explanation:
Using the cosine rule formulae;
j² = i²+k²-2i cos <J
j² = 37²+57² - 2(37)(57)cos <141
j² = 1369+ 3249- 4218cos <141
j² = 4618- 4218cos <141
j² = 4618-(-3,278)
j²= 7,896
j = √7,896
j = 88.86inches
Next is to get <I
i² = j²+k²-2jk cos <I
37² = 88.86²+57² - 2(88.86)(57)cos <I
1369 = 7,896.0996+ 3249- 10,130.04cos <I
1369 = 11,145.0996 - 10,130.04cos <I
1369 - 11,145.0996 = - 10,130.04cos <I
-9,776.0996=- 10,130.04cos <I
cos <I =9,776.0996 /10,130.04
cos<I = 0.96506
<I = 15.19
<I= 15degrees
Answer:
18 miles
Step-by-step explanation:
Find how many miles he walked this week by multiplying 2 by 6:
2(6)
= 12
Add this to 6, since he walked 6 miles last week:
12 + 6
= 18
So, in all, he will have walked 18 miles

Answer:
Minimum hour = 177 hour
Step-by-step explanation:
Given:
Paddle boats rent = $8
Paddles rent = $5 Per 24 hours
Total amount = $45
Find:
Number of hour David rent paddle boat
Computation:
8 + (5/24)n = 45
(5/24)n = 37
n = 177.6 hour
Minimum hour = 177 hour
Answer:
<em>x = 110° ; y = 49°</em>
Step-by-step explanation:
m∠ABD = m∠ADB = 35° ⇒ <em>x</em> = 180° - 2 × 35° = <em>110°</em>
m∠CDB = m∠CBD = 2y ⇒ <em>y</em> = (180° - 82°) ÷ 2 = <em>49°</em>
