Answer:
m<HJK = 40°
Step-by-step explanation:
Given:
m<HJK = 3x - 2
m<KJL = 50°
Required:
m<HJK
Solution:
m<HJK + m<KJL = 90° (complementary angle)
Substitute
3x - 2 + 50 = 90
Add like terms
3x + 48 = 90
3x + 48 - 48 = 90 - 48
3x = 42
3x/3 = 42/3
x = 14
✅m<HJK = 3x - 2
Plug in the value of x
m<HJK = 3(14) - 2 = 42 - 2
m<HJK = 40°
Answer: 9 3/4 oz
Step-by-step explanation:
12 - 2 1/4 = 9 3/4 oz
M = mile
.55m + 1.45 [less than or equal to] 35
subtract 1.45
.55m = 33.55
divide by .55
m = 61 miles or less
Using the Pythagorean theorem we can find the height of the triangle:
height = √(14^2 - 12^2)
height = √(196 - 144)
height = √52
height = 7.2
The answer would be 7.2 centimeters.
