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°
a c angle
Angle C is an acute angle.
A = 60 B = 20 C = 140 This can have a large number of answers.
The complement of an angle C is (90 - C) So the complement of an angle of 17.7° is (90 - 17.7) = 72.3°
it is angle c
how to find the measure of angle C in the following triangle
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.
the answer is 68 degrees
x=? 2x = A 4x = B 2A = B 6x = C C= 3A. or C = 1.5*B For a digit, you need to give the measurement of either A or B
c
The Law of sines: a/sin A = b/sin B = c/sin CIf the angle C in the triangle ABC is 90 degrees, then the triangle ABC is a right triangle, where c is the measure of the hypotenuse, a is the measure of the leg opposite the angle A, and b is the measure of the leg opposite the angle B.Let us observe what happens when sin C = sin 90 degrees = 1.c/sin C = a/sin A cross multiply;c sin A = a sin C divide by c both sides;(c sin A)/c = (a sin C)/c simplify c on the left hand side;sin A = (a sin C)/c = [(a)(1)]/c = a/csin A = (measure of leg opposite the angle A)/(measure of hypotenuse)From the Law of Cosine we know that cos A= (b^2 + c^2 - a^2)/(2bc). If we substitute a^2 + b^2 for c^2, we have:cos A = (b^2 + (a^2+ b^2) - a^2 )/(2ab)cos A = 2b^2 /2ab simplify;cos A = b/c = (measure of leg adjacent the angle A)/(measure of hypotenuse) Therefore tan A = sin A/cos A =(a/c)/(b/c) = (a/c)(c/b) = a/b = (measure of leg opposite the angle A)/(measure of leg adjacent to angle A). And cot A = cos A/sin A = (b/c)/(a/c) = (b/c)(c/a) = b/a = (measure of leg adjacent to angle A)/(measure of leg opposite the angle A).
