In the diagram below, KM = MO. LMNO is a square and KLM is a right- angled triangle.
(a) Find $\angle$KMO.
(b) Find $\angle$MNP.
(b) 10$^\circ$
(b) 15$^\circ$
(b) 20$^\circ$
(b) 25$^\circ$
Sorry. Please check the correct answer below.
(a) $90 ÷ 2 = 45$
$45 \times 2 =90$
$180 – 90 = 90$
It is 90$^\circ$
(b) $180 – 45 – 135 = 0$
$180 – 135 – 20 = 25$
It is 25$^\circ$
(b) 25$^\circ$
You are Right
(a) $90 ÷ 2 = 45$
$45 \times 2 =90$
$180 – 90 = 90$
It is 90$^\circ$
(b) $180 – 45 – 135 = 0$
$180 – 135 – 20 = 25$
It is 25$^\circ$
In the figure, find the sum of $\angle$a, $\angle$b, $\angle$c and $\angle$d.
Sorry. Please check the correct answer below.
$180 – 65 = 115$
$180 ÷ 3 \times 2 = 120$
$120 + 115 = 235$
You are Right
$180 – 65 = 115$
$180 ÷ 3 \times 2 = 120$
$120 + 115 = 235$
