Answer:
A multiplicative inverse of a real number x is a real number y such that xy = 1. ... ((NOT GOOGLING DEF))
Step-by-step explanation:
"For every real number x, if x 0, then there is a real number y such that xy = 1.”
Answer:
1. angle AEB and angle DEF
2.angle AEB and angle CEB
3. angle AEF and angle DEF
4. 120 degrees - vertical angles have the same degree
5. 13 degrees - vertical angle
6. 180-110 = 70 degrees - supplementary
7. 180-65 = 115 degrees - supplementary
Step-by-step explanation:
vertical angle = angles that are opposite of each other where two lines cross
complementary angle = angles that make up the sum of 90 degrees
supplementary angle = 2 angles with the sum of 180 degrees
Answer:
The measurement of EF is 1.98 units
Step-by-step explanation:
In Δ DEF
∵ m∠E = 90°
∴ FD is the hypotenuse of the triangle
∵ m∠D = 26°
∵ EF is opposite to angle D
- We can use the sine ratio to find it
∵ sin D = 
⇒ (opposite side / hypotenuse)
∵ FD = 4.5 units
∴ sin(26) = 
- Multiply both sides by 4.5
∴ 4.5 sin(26) = EF
∵ sin 26° ≈ 0.44
∴ 4.5(0.44) = EF
∴ 1.98 = EF
The measurement of EF is 1.98 units
