この英文から、なぜ筆者のプランは毎月100ドル以上かかったと言えないのか教えてほしいです

B You are a college student going to study in the US and need travel insurance. You find this review of an insurance plan written by a female international student who studied in the US for six months. 0 There are many things to consider before traveling abroad: pack appropriate clothes, prepare your travel expenses, and don't forget medication (if necessary). Also, you should purchase travel insurance. Imam gavo 0012 1ovo od 1200 sla When I studied at Fairville University in California, I bought travel insurance from TravSafer International. I signed up online in less than 15 minutes and was immediately covered. They accept any form of payment, usually on a monthly basis. There were three plans. All plans include a one-time health check-up. gisinal The Premium Plan is $100/month. The plan provides 24-hour medical support through a smartphone app and telephone service. Immediate financial support will be authorized if you need to stay in a hospital.

However, it was nice to get the optional 15% discount because I paid for six months of coverage in advance. If your budget is limited, you can choose the Economy Plan, which is $25/month. It has the 24-hour telephone support like the other plans but only covers emergency care. Also, they can arrange a taxi to a hospital at a reduced cost if considered necessary by the support center. I never got sick or hurt, so I thought it was a waste of money to get insurance. Then my friend from Brazil broke his leg while playing soccer and had to spend a few days in a hospital.

◯してる部分がどういうことか、教えて下さい。

練習問題 5 313 鋭角三角形ABC がある. 頂点Aから辺BCに下ろした垂線の足をいと し、さらにHから辺 AB AC に下ろした垂線の足をそれぞれP,Qとす る. (1) A,P,H,Qは同一円周上にあることを示せ. (2) P, B, C, Qは同一円周上にあることを示せ. 精講 この問題では、「内接四角形の定理の逆」 を使ってみましょう。あ る四角形の 「対角の和が180°」 であれば、その四角形は円に内接 することがわかります。 練習問題 4 (2)で見たように、 「対角の和が180°」であ ることは「ある内角がその“対角の外角”と等しい」ことと同じであることも 頭に入れておくといいでしょう。 解答 (1) ∠APH+∠AQH=90°+90°=180°であるから, 内接四角形の定理の逆より、四角形APHQ は円 に内接する.つまり,A,P,H,Qは同一円周上 にある. A (2)A,P,H,Qは同一円周上にあるので,円周角 の定理よりも B HA ∠AQP=∠AHP ••••••① また,∠AHB=90° ∠APH=90°より, ∠AHP=90°-∠BAH=∠ABH ......② ① ② より ∠AQP=∠PBC. 四角形 PBCQ B' H は1つの頂点の内角がその 「対角の外角」 と等しいので,内接四角形の定 理の逆より,四角形 PBCQ は円に内接する.したがって,P, B, C, Qは 同一円周上にある.
