Answer:
x = 3
Step-by-step explanation:
Since all 3 sides of the triangle are congruent then the triangle is equilateral
The 3 angles are congruent and equal to 60°, thus
25x - 15 = 60 ( add 15 to both sides )
25x = 75 ( divide both sides by 25 )
x = 3
Answer:
Angle one = 78°
Angle two = 102°
Step-by-step explanation:
180° - 24° = 156°
156° / 2 = 78°
78°+24° = 102°
The second angle can also be found by subtracting 78° from 180°
180° - 78° = 102°

Answer:
127
Step-by-step explanation:
The sum of 7 terms of the series 1 +2 +4 +... with first term 1 and common ratio 2 is given by ...
Sn = a1 × (r^n -1)/(r -1) . . . . . . first term a1, common ratio r
S7 = 1 × (2^7 -1)/(2 -1) = (128 -1)/1 = 127
