Answer:
X is equal to 5
Step-by-step explanation:
If DE is a midsegment of the triangle, then segments AD and DB are congruent, therefore they have the same value.
Answer:
TRUE
Step-by-step explanation:
tanθ = 1/cotθ
cotθ = 0 when θ = ±(1/2)π, ±(3/2)π, … ±[(2n+1)/2]π.
∴ tanθ is undefined when θ = ±[(2n+1)/2]π.
secθ = 1/cosθ
cosθ = 0 when θ = ±(1/2)π, ±(3/2)π, , …, ±[(2n+1)/2]π.
∴ secθ is undefined when θ = ±[(2n+1)/2]π.
The tangent and secant functions are undefined for the same values of θ.
Answer:
11918
Step-by-step explanation:
well plug em eqaul to each other to get x = 156
156 + 12 = 178
156 squared - 144 = 24192
24192 - 356 = 23836
divide by two =
Answer:
90°
Step-by-step explanation:
Ok, I get it now.
Draw two perpendicular lines. Starting at any of the right angles, name them 1, 3, 2, 4 going around in order.
Now you have vertical angles 1 and 2, vertical angles 3 and 4, and angle 3 is adjacent to angles 1 and 2. this is exactly what the description states.
Since angles 3 and 4 are right angles, then all angles are right angles.
m<1 = m<2 = m<3 = m<4 = 90
m<4 + m<1 - m<2 = 90 + 90 - 90 = 90
Answer: 90°
Answer:
1 yard is more.
Step-by-step explanation:
There are 3 ft in 1 yard, and three is more that two so, a yard is more.
