Answer:
No solution
Step-by-step explanation:
Because BDC is 20, and DC = DB, DBC is also 20 degrees. ABD would then be 160 since DBC and ABD has to equal 180. You know ADB is 35 so 160 + 25 + x has to equal 180. But 160 + 25 is already 185, and x can't be negative, so no solution.
<span>1st one: x, 2nd wud b : x+2
if its sum is 56
means:
x+ (x+2) = 56
2x = 56 -2
x= 54/2
x= 27
27 is the first odd number and the second is 27 + 2 i.e. 29
------------------------
sum of two numbers is 72
let smaller: x
larger: 4+x
its sum:
(4+x) + x = 72
4+2x=72
x= 68/2
x= 34
smaller is 34 and the larger is 34 + 4 = 38

Sin. Cos. Tan.
1) we have a opposite and adjacent so we're going to use tan.
48÷Tan(73)=14.6750
2) we have the hypotenuse and the adjacent so we use cos.
40×cos(70)=13.6808
