8 angles are formed by the transversal
Answer:
Therefore the value of x is 4.
Step-by-step explanation:
Given:
AO = 5x - 8
BO = 3x
AM ≅ BM
To Find :
x = ?
Solution:
In Δ AMO and Δ BMO
AM ≅ BM ……….{Given}
∠ AMO ≅ ∠ BMO …………..{measure of each angle is 90° given}
MO ≅ MO ……….{Reflexive property}
ΔAMO ≅ Δ BMO ….{ By Side-Angle-Side test}
∴ AO ≅ BO ...{corresponding sides of Congruent triangles or CPCT}
on substituting the values we get
Therefore the value of x is 4.
The cosine repeats itself every 360 degrees, and it mirrors at 0 and 180 degrees. It inverts around 90 and 270.
So without using a calculator, you can tell that:
cos(520)=cos(520-360)=cos(160)
cos(160) = cos(180-20) = cos(180+20) = cos(200)
cos(160) is NOT equal to cos(20), it would be -cos(20).
cos(160) = -cos(20) = -cos(-20)
So C is the only one unequal.
Answer:
Step-by-step explanation:
Answer:
13/20 Hours
Step-by-step explanation:
you have to find a common denominator. (20) You do 4x5 and 5x4 both equal 20. Then you do 1x5=5 and 2x4=8 then 8+5=13 then you make your fraction which is 13/20.
