Answer:
CD ≈ 26.0 cm
Step-by-step explanation:
using the sine ratio in right triangle ABD
sin35° = =
=
( multiply both sides by BD )
BD × sin35° = 12 ( divide both sides by sin35° )
BD = ≈ 20.92 cm
using the sine rule in Δ BCD
=
, that is
=
( cross- multiply )
CD × sin52° = 20.92 × sin102° ( divide both sides by sin52° )
CD = ≈ 26.0 cm ( to 3 significant figures )
Harry can first substitute 30 for t
He can then multiply by 30 to get a product of 10
Since, 10 is not equal to 15, Harry's solution is not correct.
<em><u>Solution:</u></em>
Given that,
Harry solves the equation:
He says the solution is 30
We have to check if his answer is correct or not
<em><u>Fill in the blanks to explain how Harry can check whether his solution is correct</u></em>
