In ∆xyz if angle x= 2x+10°, angle y= 3x+10° angle z= 5 x-30° find the measure of angles XYZ uu About the author Adalyn
Step-by-step explanation: sum of all angles in ️ triangle are 180 degrees xyz= z+x+y=180 (2x+10)+(3x+10)+(5x-30)=180 10x+10+10-30=180 10x-10=180 10x=180+10 10x=190 x=19 (2x+10)=2×19+10=48 (3x+10)=3×19+10=57 (5x-30)=5×19+10=105 48+57+105=180 Reply
Answer:
The answer will be 4x-90
Step-by-step explanation:
Step-by-step explanation:
sum of all angles in ️ triangle are 180 degrees
xyz= z+x+y=180
(2x+10)+(3x+10)+(5x-30)=180
10x+10+10-30=180
10x-10=180
10x=180+10
10x=190
x=19
(2x+10)=2×19+10=48
(3x+10)=3×19+10=57
(5x-30)=5×19+10=105
48+57+105=180
