Answer:
50
Step-by-step explanation:
If R is 65, then T must also be 65 because both of the sides are congruent. 65+65=130 and all angles on a triangle add to 180. Therefore 180-130 is 50
Answer:
1 7/24.
Step-by-step explanation:
7/8 + 3/4 - 1/3 The LCD of 3,4 and 8 is 24 so we have:
21/24 + 18/24 - 8/24
= 39/24 - 8/24
= 31/24
= 1 7/24.
Answer:
{f, a}
Step-by-step explanation:
Given the sets:
X = {d, c, f, a}
Y = {d, e, c}
Z ={e, c, b, f, g}
U = {a, b, c, d, e, f, g}
To obtain the set X n (X - Y)
We first obtain :
(X - Y) :
The elements in X that are not in Y
(X - Y) = {f, a}
X n (X - Y) :
X = {d, c, f, a} intersection
(X - Y) = {f, a}
X n (X - Y) = elements in X and (X - Y)
X n (X - Y) = {f, a}
