Hey there!
In an isosceles triangle the 2 base angles are congruent, therefore angle B would measure 50 degrees just like the measure of angle A.
Thanks for using Brainly!
The second one would be the answer. You want to plug in for this question. You can divide over the five leaving you with (x-2)^2 =25. Since you are squaring this answer, you want to get either 5 or negative five. Both -3 and 7 will do that.
Answer: Equation : t - 75 = 325 , Solution: t=400, 400 degree F
t= original temperature
Step-by-step explanation:
Answer:
-8
Step-by-step explanation:
So first off, x is 2-4. So that's the default. It would be -2. If you multiply -2 by 2, it is -4.
Minor Arc AC = 110 degrees (given)
As indicated in the hints,
OA=OC => OAC=OCA=(180-110)/2 = 35
Similarly,
OAB=OBA=(48-35)=13
=>
OBC=OCB=(180-35-35-13-13)/2=(180-96)/2=84/2=42
=>
Angle B = 13+42 = 55 degrees
Check:
55+55+35+35+13+13 = 180 degrees (angles of a triangle) ok.
