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 :)
20. SR = 17
22. TR = 5 and PR= 10
23. ST=9.5
24. X=1.5
for 23, the length of QS is 19, and ST is half of that length. so you divide 19/2 and get 9.5
for 24, i found it difficult to explain but i included a picture of my work. i know it may not help but it's all i've got.
Answer:
214.
Step-by-step explanation:
To get Surface area take
(cross section area) × 2 +(perimeter of crossection area × length)
the cross section area is a triangle
so area of a triangle =1/2 base times height
1/2×8×2=8
let's get perimeter of cross section
the cross section is still at triangle so let's find its perimeter.
5+5+8=18
18×length of which is 11
18×11=198
and 188 + 16=214. that's the answer
maybe you can get a expression from the work that I've just done cuz I can't see the answers clearly in the picture you have taken.if you don't mind just send the picture back then I'll get the answer.
Answer:
B
Step-by-step explanation:
They are literally the same quadrilateral. Same side lengths and angle measures.
The solution to your problem is as follows:
y = –x² + 6x –11
same objective : f(x) = a(x - h)^2 + k as V(h,k) as vertex
<span>
so here: </span>
<span>
y = –x² + 6x – 11 </span>
y = –(x² - 2*3x + 3^2) – 2
<span>y = - (x - 3)^2 - 2 -----------> h = 3 and k = -2
</span>
Therefore, the coordinates of the vertex for the graph is (3,-2).
