Answer:
3/4
Step-by-step explanation:
Step-by-step explanation:
1) the rule: m∠1+m∠2+m∠3=180°;
2) according to the rule above: m∠P+m∠Q+m∠R=180°;
x+x+43+2x-15=180°; ⇔ 4x=152°; ⇒ <u>x=38°</u>;
3) the angles: P=2x-15=<u>61°;</u> Q=x+43=<u>81°</u>; R=x=<u>38°</u>.
Answer:
25
Step-by-step explanation:
the formula for the hypotenuse of a triangle is
a^2+b^2=c^2
plug in what we know
7^2+24^2=c^2
49+576=c^2
625=c^2
c=25
