it is angle c
i dont no
If we are talking about a triangle here, then: A = 61º B = 45º C = 74º But, since you did not specify, there is an infinite number of answers.
This doesn't ask any question but I assume you want to know the measures of angles ABC.Well if C is 15 degrees LESS than half of angle A then the algebraic equation would look something like this:Let x = measure of angle B then 4x = measure of angle A, since angle A is four times angle Bthen 2x (half the measure of angle A = 4/2) - 15 = measure of C.Basic Knowledge:angle A+ angle B+ angle C=180°180 degrees = total measure of angles in a triangle4x° + x° + (2x - 15)° = 180°SOLVE for X!STEP 1: always combine (add/subtract) like terms7x°-15+15=180°+15(isolate the variable by adding 15 on both sides of the equation)_________7x°/7+0 = 195°/7 (solve for x by dividing 7 on both sides of the equation)_________x ≃ 27.86° or = (27 6/7)° = measure of angle B4x ≃ 111.44° = measure of angle A2x-15 ≃ 55.72°-15 ≃ 40.72° = measure of angle C**add them all up together, they would add up to 180.02° because x actually equals 27.857142857142857142.....Now if C is 15 degrees MORE than half of angle A then the algebraic equation would look something like this:again; Let x° = measure of angle Bthen 4x° = measure of angle A, since angle A is four times angle Bthen 2x (half the measure of angle A = 4/2) +15 = measure of C.4x° + x° + (2x + 15)° = 180°SOLVE for X! (same steps, just watch for the signs)7x°+15-15=180° -15 (subtracted 15 on both sides)_________7x°/7 +0 = 165°/7 (divided 7 on both sides)_________x ≃ 23.57° or = (23 4/7)° = measure of angle B4x ≃ 94.28° = measure of angle A2x+15 ≃ 47.14° +15 ≃ 62.14° = measure of angle C**add them all up together, they would add up to 179.99° because x actually equals 23.571428571428571428.....See the pattern?? and the difference??
B = 3A : C = 0.9 x 6A Therefore 180 = A + B + C = A + 3A + 5.4A = 9.4A : A = 180 ÷ 9.4 = 19.15° (2dp) Then B = 57.45° and C = 103.40°
