I need help with 9-10

Find the measure of the 3rd anele and name the sides accordimeh ol sides a 2viem, b 4em, e-2enn with angles 30 and 90 lol Circle the correct description of the triangle: (right, acute obtuse) and (aquilalenii isinedes, scalene)

Solution

a=23 , b=4 ,c=2

given 2 angles are 30⁰,90⁰

sum of three angles in triangle =180⁰

30⁰+90⁰+third angle =180⁰

third angle = 180⁰-30⁰-90⁰

third angle = 60⁰

order of sizes of angles in triangles will be in the same order of sizes of opposite sides

c<a<b

so angleC<angleA<angleB

30⁰<60⁰<90⁰

A=60⁰,B=90⁰,C=30⁰

Triangle is acute scalene
