Answer:
<h2>
cos 30°= 0.866</h2>
Step-by-step explanation:
Step one:
Applying the SOH CAH TOA principle
assuming all dimensions are in cm
Step two:
Given data
opposite= 1 cm
hypotenuse= 2 cm
<h3>we can now solve for θ</h3>
Sin(θ)= opp/hyp
Sin(θ)= 1/2
Sin(θ)= 0.5
θ= sin-1 0.5
θ= 30°
hence from tables cos 30°= 0.866
20 grams
Triangle is half of rectangle therefore triangle is 40 grams
And since triangle is double the weight of the circle is half of 40 which is 20 grams
Answer:
y = 3x + 2
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 3 and c = 2 , then
y = 3x + 2 ← equation of line
Answer:
<h2>
C. y = 54°</h2>
Step-by-step explanation:
y + y + 72 = 180
2y = 180 - 72
y = 108/2
y = 54°
