Answer:
a) 60 degrees
Step-by-step explanation:
b) The triangle shown is an equilateral triangle as all the sides are the same. This means that all the angles are the same as well.
Angles in a triangle add up to 180 degrees. There are 3 angles. Each angle is 60 degrees.
Angle x is an exterior corresponding angle and hence, that is why x = 60 degrees.

Answer:
<h3>The estimate would be 3-0= nothing, so her answer is not reasonable.</h3>
Step-by-step explanation:
Given the expression written by Elizabeth as 3.3 - 0.21= 1.2, to check if Elizabeth expression is reasonable or not, we need to check if her answer is close to or equal to the answer of the diiferebce between 3.3 - 0.21.
Converting 3.3 and 0.21 to fraction
3.3 = 33/10
0.21 = 21/100
Taking the difference of both fractions

Hence 3.3 - 0.21 = 3.09 ≈ 3.0 (to nearest whole number). Comparing Elizabeth answer which is 1.2 to the answer f=gotten, it can be seen that her answer is far from the right answer with a difference of about 1.8 (3.0-1.2). <u>This large difference makes Elizabeth answer unreasonable.</u>
The original price was £348.
Adding 20% to to something is the same as multiplying by 1.2
Therefore, £290 * 1.2 = £348
The sides could be 12 centimeters
