Recall that the sum of the measures of the angles of a triangle is 180°. In the triangle below, angle Chas the same measure as a
Effectus [21]

The measure of each angles a,b and c are 32°, 74°  and 74°  respectively.

What is triangle?
Three edges and three vertices define a triangle as a polygon. One of geometry's fundamental shapes is this one. The symbol for an ΔABC triangle is A, B, and C.
Any three points determine a distinct triangle and a distinct plane in Euclidean geometry when they are non-collinear (i.e. a two-dimensional Euclidean space). To put it another way, each triangle is contained in a plane, and there is only one plane that includes that particular triangle. All triangles are contained in one plane if and only if all geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces. Except as otherwise specified, the subject of this article is triangles in Euclidean geometry, more specifically, the Euclidean plane.

Let angle b be x

Therefore angle c will also be  x [as given b and c are equal] and angle a will be x - 42°.
Now as we know that the sum of the measures of the angles of a triangle is 180° therefore,

x + x + x - 42° = 180°

=> 3x = 222°

=> x = 74°  which is angle b and c

and angle a is (74 - 42)°  =32°

1.5d + 3.25 = 1 + 2.25d ---What are the steps to find x?
yuradex [85]
Do u mean d?

1.5d +3.25 = 1 +2.25d  
3.25 = 1 + .75d              -1.5d on both sides
2.25 = .75d                      subtraction 1 on both sides
3 = d                                  divide both sides by .75
