You would first turn it into an improper fraction, to do this you leave the denominator(bottom number) then times it by your variable and add the numerator(top number)
Ex:
1 3/4x1/3= 7/12
Answer:
65 degrees
Step-by-step explanation:
The question is not complete but we can assume that m<4 and m<8 are complementary i.e they both act at right angle.
If the both act at right angle, then m<4 + m<8 = 90
Given
m<4 = 25°
Substitute into the formula
m<4 + m<8 = 90
m<8 = 90 - m<4
m<8 = 90 - 25
m< 8 = 65 degrees
Hence the measure of m<8 is 65 degrees
<em>Note that we assumed that both angles acts at right angles </em>
Answer:
The value of x is 12
Step-by-step explanation:
To find the value of x, we need to note that the interior angles are equal to 180. We also know that angle R is equal to 180 - (8 + 6x). So we can add all of this together and set equal to 180.
180 - (8 + 6x) + 4x + 2 + 30 = 180
180 - 8 - 6x + 4x + 2 + 30 = 180
-2x + 24 = 0
-2x = -24
x = 12
Answer:
Area of segment = 9.8 cm² (Approx.)
Step-by-step explanation:
Given:
Angle θ = 120°
Radius of circle = 4 cm
Find:
Area of segment
Computation:
Area of segment = [θ/360][π][r]² - [1/2][r²][sinθ]
Area of segment = [120/360][3.14][4]² - [1/2][4²][sin120]
Area of segment = [0.333][3.14][16] - [0.5][16][0.866]
Area of segment = 16.7299 - 6.28
Area of segment = 9.8019
Area of segment = 9.8 cm² (Approx.)
