Answer:
x = 11
Step-by-step explanation:
right triangle ABC
using Pythagoras' identity
BC² = 7² + 24² = 49 + 576 = 625 ( take square root of both sides )
BC = 
= 25
Since the triangles are congruent then corresponding sides are congruent.
ST = BC , that is
3x - 8 = 25 ( add 8 to both sides )
3x = 33 ( divide both sides by 3 )
x = 11

Sin 270 = -1, cos 270 = 0, tan 270 is undefined.
If it’s just the probability of 1 question it would be 1/5 but if they guess on every question it’s 100/500
Shouldn’t there be a total of 61 people being surveyed?The 6 won’t be in the circles but it’ll be in the diagram.Since the qn states that there’s no people with both (from what i’m assuming from the qn)We will group those with a brother in one circle and call it “A” and those with a sister as another circle and call it “B”.So the diagram should look something like this ⬇️ don’t mind my handwriting
