Answer:
Nine hundred seven hundred thousand and three
Step-by-step explanation:
If BD=DC that means triangle CDB is isosceles triangle and the measure of angles ∡CDB and ∡BCD is the same
∡CDB=∡BCD=70°The angles ∡ADB and ∡CDB are adjacent and suplementary angles
It means
∡ADB + ∡CDB = 180°
∡ADB = 180° - ∡CDB
∡ADB = 180° - 70°
<u>∡ADB = 110°</u>
Answer:
ST = 8 m
Step-by-step explanation:
Since ∆PQR is congruent to ∆STU, therefore, the three sides of ∆PQR would be congruent or equal to the corresponding three sides of ∆STU.
PQ corresponds to ST.
Therefore, PQ is congruent to corresponding side ST, which is 8 m
ST = 8 m
Answer:
17.3
Step-by-step explanation:
a² = b² + c² - 2bc cos A
t² = 11² + 14² - 2(11)(14) cos 87
t² = 121 + 196 - 308 (.052336)
t² = 300.88
t = 17.3
-9x from both sides
5x+2=-3
-2 from both sides
5x=-5
x= -1
