Answer:
60 and 35
Step-by-step explanation:
Let:
First number = x
Second number = y [ y > x ]
According to question:
x + y = 95
= > y = 95 - x .... ( i )
y = x + 25 ...... ( ii )
From ( i ) and ( ii ) we get:
95 - x = x + 25
= > 2x = 70
= > x = 35
y = 95 - x [ x = 35 ]
= > y = 60
Therefore numbers are 60 and 35.

Answer:
75°
Step-by-step explanation:
∠DGF = 2* ∠DEF
10x + 50 = 2(9x - 15)
10x + 50 = 18x - 30
50 = 18x - 30 - 10x
50 = 8x - 30
8x - 30 = 50
8x = 50+30
8x = 80
x = 80/8
x = 10
∠DEF = 9x - 15
= 9*10 -15
= 90 - 15
= 75°
Answer:
12
Step-by-step explanation:
There are 4 points, so there are C(4,2) = 4C2 = 6 pairs of
points and since two equilateral triangles can be drawn having
that pair of points as vertices, there are 12 equilateral
triangles that can be drawn having two vertices in the set
{(0,0), (0,1), (1,0), (1,1)}.
The second choice...... Let me know if it’s right
