Step 1. Multiply 31.50 by .08. (31.50)(.08)=2.52

Step 2. Subtract 2.52 from 31.50. 31.50-2.52=28.98

Step 3. Multiply 28.98 by .08. (28.98)(.08)=2.32

Step 4. Add 2.32 to 28.98. 28.98+2.32=31.30

bekas [8.4K]

Answer:

134°

Step-by-step explanation:

∠BAC = ∠BCA because it is an isosceles triangle

∠XCA = ∠XAC .  Congruent angles

∠XAC = 1/2(46) = 23° .  because CE bisects ∠ C

∠XCA = 23°

180° - 23° - 23° = 134° .  Sum of all angles in a triangle is 180°

If my answer is incorrect, pls correct me!
