Question

From the sum of
In a triangle XYZ, sides XY and YZ are of equal length. If ZX= 40°, find the measure of LY
and ZZ.

Find the value of a +bº - 3abc, given that a = 3. b = 2. and c = 1
Find the perimeter of a triangle whose sides are 2x2 + 3x + 1,x2 + 7 and 3x2 - 2x + 3
​

Answer 1

Answer:

the triangle with two side equal is isosceles. and it two angle is equal. and 1 angel is given 40 degree

therefore 180-40=140

now divide 140/2 =70 degree

so lm and zz equal to 70 degree each
