Answer:
Step-by-step explanation:
The letter A has at least 1 line of symmetry
Answer:
first step - make x² the subject of the formula
x² = 25
second step :
find the square root of both sides
√x² = √25
x = 5
Step-by-step explanation:
Answer:
x = 70°
Step-by-step explanation:
The given triangle has 2 equal sides and is therefore isosceles.
The base angles are equal, both 55°
To find x subtract the sum of the 2 angles from 180
x = 180° - (55 + 55)° = 180° - 110° = 70°
