Answer:
In ∆ABD and ∆ACD
<BAD =<CAD ( each are half of <A )
<D=<D ( each equal to 90°)
AD = AD ( common)
So ∆ ABD is congruent to ∆ ACD.
Then AB =AC (by C.P.C.T)
Hence,∆ABC is an iso - sceles triangle.
Answer:
Arc ECG is the major arc
Step-by-step explanation:
Arc ECG is made by an angle which is greater than 180°.
All the other arcs listed are made by angles which are 180° or less than.
The greater the angle measure the greater the arc length.
Sorry it's a bit messy. but I hope you understand and it will help
X=8 i did mental math but 56x-16-x=424
+16 +16
55x=440
/55 /55
x=8
For this type of question, you just need to multiply the percentage with the number
so, the calculation would be
47.2% x 300
47.2/100 x 300
47.2 x 3
= 141.6
