find angle 2 and angle 1, and the values of angle x and y!

Step-by-step explanation:

An obtuse triangle is a triangle that has a single obtuse angle, which is an angle that measures more than 90 degrees and less than 180 degrees. Obtuse triangles, also referred to as oblique triangles, can be recognized by their having a single significantly larger angle and two smaller angles. Since every triangle has a measurement of 180 degrees, a triangle can only have one obtuse angle. You can calculate an obtuse triangle using the lengths of the triangle's sides.

Square the length of both sides of the triangle that intersect to create the obtuse angle, and add the squares together. For example, if the lengths of the sides measure 3 and 2, then squaring them would result in 9 and 4. Adding the squares together results in 13.

Square the length of the side opposite the obtuse angle. For the example, if the length is 4, then squaring it results in 16.

Part (a): number of minutes of butterfly strokes is xnumber of minutes of breaststrokes is ywe are given that: he practices breaststrokes 20 minutes more than butterfly stroke. this means that: y = 20 + xwe are also given that: he practices a total of 50 minutes. this means that: x + y = 50based on the above, the pair of linear equations representing the situation would be as follows: x + y = 50 > equation iy = 20 + x > equation iipart (b): we need to get the values of x and y.to do so, substitute with equation ii in equation i and solve for x as follows: x + y = 50x + 20 + x = 502x = 50 - 202x = 30x = 15substitute with x in equation ii to get y as follows: y = 20 + xy = 20 + 15y = 35based on the above: number of minutes of butterfly strokes = x = 15 minutesnumber of minutes of breaststrokes = y = 35 minutespart (c): we are given that number of butterfly stroke = x = 45 minuteswe know that number of breaststrokes is 20 more than butterfly strokes.butterfly strokes = 20 + 45 = 65 minutestherefore, ted would need a total of 45 + 65 = 110 minutes of practicesince we know that he practices 50 minutes only, therefore, this is not possible.hope this : )
