Answer:
12/5
Step-by-step explanation:
The reciprocal is flip the fraction
5 /12 has a reciprocal of 12/5
Answer:
As shown in picture:
BC = BA => triangle ABC is isosceles => angle BCA = angle BAC
DC = DA => triangle ADC is isosceles => angle DCA = angle DAC
=> C = BCA + DCA = BAC + DAC = A
Other wise, the sum of 4 internal angles of a quadrilateral is equal to 360 deg.
=> C + A = 360 - 100 - 45 = 215
=> C = A = 215/2 = 107.5 deg
Hope this helps!

Step-by-step explanation:
Answer:
a - yes
b - no
Step-by-step explanation:
triangle inequality theorem - the sum of any 2 sides of a triangle must be greater than the measure of the third side
For a
5 + 4 must be greater than 7 for the set to be measures of the sides in a triangle
5 + 4 = 9
9 is greater than 7 therefore 4,5, and 7 can be measures of the sides in a triangle
For b
3 + 2 must be greater than 6 in order for the set to be measures of the sides in a triangle
3 + 2 = 5
5 is less than 6 therefore 2,3 and 6 can not be measures of the sides in a triangle
