A) First option

Opposite - 2

Hypotenuse - a

OH - SOH

SIn(45) = 2/h

x h, then ÷ sin45

h = 2/sin45

h= 2 root 2

=2.83 to 2d.p

Use Pythagoras Theorem to find a because b=2 as we're shown an isosceles triangle with those little dashes, on two side lengths.

Hope this helps!

Find the distance between the points given.

Maru [420]

Use the distance formula

$d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2$

Input corresponding numbers

$d = \sqrt {\left( {2- 6} \right)^2 + \left( {5-8} \right)^2$

Solve

$d = \sqrt {\left( {-4} \right)^2 + \left( {-3} \right)^2$

$\sqrt{16 + 9}$

$\sqrt{25} = 5\\\\ d=5$

So, the distance between the points given is 5
