Step-by-step explanation:
a) BEC=90°(right angle triangle)
total degrees of a triangle is 180°
therefore let the missing angle be x
it will be 90+27+x=180
value of X=63°
therefore <BCE=63°
b) since ΔBAD is an
isosceles triangle
ABE must also be 52°total degrees of a triangle is 180°
let the missing angle be Y
it will be 52+52+Y=180
value of Y is 76
therefore <BAD=76°
Answer:
The first one!
Step-by-step explanation:
Answer: 16 science problem and 26 math problems
Step-by-step explanation: First, subtract 10 from 42. When you do this, you get 32. Next, divide 32 in half. You'll get 16 for each. Finally, add 10 to one of the 16's and you'll get 26 and 16.
Answer:
d
Step-by-step explanation:
add all the angles you know to get 480
the number of angles - 2 x 180 to get 720
720-480=240
divide 240 by 3 to get x
