Step-by-step explanation:
In triangles BAD and BCD ,
BD=BD (common)
angle BDA= angle BCD {90°each(given)}
AD=DC (given)
.•. traingle BAD is congruent to triangle BCD (SAS criterion)
Hence , angle A = angle C (CPCT)
U^2(2u+3)+7(2u+3)
(u^2+7)(2u+3)
Option 3 (1/4 x 60) since 59 is close to 60 and 25% can be rewritten as 1/4
The first one doesn’t represent a function. This is because it uses the same x-value twice.
