A straight line is 180°, so you add these two angles together because they make a straight line:
3x° + 75° = 180°
To find "x", isolate/get the variable "x" by itself in the equation. Subtract 75° on both sides
3x° + 75° - 75° = 180° - 75°
3x° = 105° Divide 3 on both sides to get "x" by itself
x = 35°
PROOF
3x° + 75° = 180° Substitute/plug in 35 into "x" since x = 35°
3(35)° + 75° = 180°
105° + 75° = 180°
180° = 180°
Answer:
WX < YW < XY
Step-by-step explanation:
<h2>Angle sum property</h2>
Sum of all angles of triangle = 180
114 + 53 + ∠y = 180
167 + ∠Y = 180
∠Y = 180 - 167
∠Y = 13
The side opposite to smallest angle is shortest.
Angles in ascending order: ∠Y < ∠X < ∠W
Sides in ascending order: WX < YW < XY
Answer:
Option 1
Step-by-step explanation:
x⁴ + 2x³ - 5 + 3 + 7x³ + x⁴
2x⁴ + 9x³ -2
<span>The sample proportion of the the students that took fewer than the mean number of electives is given by the number of people who took less that the mean number of electives (i.e. 7.63) divided by the total number of students in the sample (i.e. 19).
The total number of people who took less than 7.63 electives is 10.
Therefore, the required sample proportion is 10 / 19. </span>
Think of fractions as an equation for a decimal. So treat it as such.
32/75=0.427
3/11=0.28
-5/8=-0.625
-7/10=-0.7
21/7=3
-179/99=-1.81
