Question

the three angles in a triangle are the ratio 1:3:4. 5. find them​

Answer 1

Answer:

measure of angles will be 22.5 , 67.5 and 90 respectively

Step-by-step explanation:

Total measure if angles in a triangle

$180$

measure of first angle

$180 \times 1 \div (1 + 3 + 4)$

that is

$180 \times( 1 \div8) = 22.5$

then 2nd angle

$22.5 \times 3 = 67.5$

then 3rd angle

$22.5 \times 4 = 90$
