Find the value of a and b
Leokris [45]

Answer:

a=10

b=37

Step-by-step explanation:

a+5 is equal to the opposite line, 15. 10+5=15 therefore, a must equate to 10

3b is the same angle as 111 therefore 3*b has to equate to 111. 111 divided by 3 equals 37. B has to then equate to 37 to make the proper angle.

Hope my explanation wasn't too confusing, and hope this helps! Good luck!!!

Can someone please answers these questions
Zarrin [17]
Try this option (<u>not for all the tasks!</u>):
1) rule for n-angle is: S=180°(n-2), where n - number of the sides. S₁₅=180*13=2340°;
2) S₂₅=180*23=4140°;
4) this is deltoid;
5) this is paralelogram;
6) x=130°; y=50°;
10) x=90°; y=30° (it is deltoid);
12) not enough info for parallelogram (the same for deltoid);
14) it is enough: according to a property of a parallelogram (it means that a square and rombus are parallelograms);
15) it is enough according to the properties of parallelograms;
16) x=2; y=1;
18) poit S(0;0); point T(b+c;d). The coordinates of the midpoint are (0.5b+0.5c;0.5d); slope=arctg(d/(b+c)).
