In △ABD and △ACD, we have
DB=DC ∣ Given
∠ADB=∠ADC ∣ since AD⊥BC
AD=AD ∣ Common
∴ by SAS criterion of congruence, we have.
△ABD≅△ACD
⇒AB=AC ∣ Since corresponding parts of congruent triangles are equal
Hence, △ ABC is isosceles.
Answer:
B = 50°
Step-by-step explanation:
Because all the angles in every triangle added together equals 180°, you would divide m∠CAB (62°) by 2, giving you 31°, then add the 99° to the 31°, and you have 130°, and just by looking at it, you can see that the ∠ABD =50°
Hope this helps :)
Answer:12000
Step-by-step explanation:
During the Playoff the schools football team has on average 30% their games than during the regular season
The average for this year's playoffs attendance was 15,600 fans
To get the number of fans during a regular season goes thus:
Since there is an increase of 30%, we add 100% to 30% which gives:
100% + 30% = 130%
= 15600 ÷ 130%
= 15600 ÷ 130/100
= 15600 × 100/130
= 15600 × 0.7692
= 12000
There are 12000 fans during a regular season
Answer:
x = -2
Step-by-step explanation:
The segments described in the question are equidistant (meaning they are the same length). Therefore, using algebraic techniques, we can set these two equal to each other and solve for x.
4x - 8 = 6x - 4 Combine like terms by subtracting 6x from both sides.
-2x - 8 = -4 Combine like terms by adding 8 to both sides.
-2x = 4 Divide by -2 on both sides of the equation.
x = -2
